1 35126185 Serum and glucocorticoid-inducible kinase 3 (SGK3) is involved in maintaining podocyte function by regulating the protein levels of podocin and CD2-associated protein.
2 35126185 Nephrin is also one of the slit diaphragm proteins of podocytes, but whether SGK3 participates in podocyte injury by regulating the levels of nephrin remains unclear.
3 35126185 In this study, we focused on whether SGK3 affects nephrin levels and the mechanisms involved in the same.
4 35126185 In the kidneys of adriamycin (ADR)-induced podocyte injury mouse model, the protein levels of SGK3 and nephrin were significantly decreased.
5 35126185 In ADR-treated conditionally immortalized mouse podocyte cells (MPCs), the protein levels of nephrin and SGK3 were inhibited, while the constitutive expression of SGK3 reversed the ADR-induced decline in nephrin protein levels.
6 35126185 Furthermore, ADR treatment or SGK3 inactivation enhanced the ubiquitin-proteasome degradation of nephrin in MPCs, and dramatically activated downstream effector proteins of SGK3, neural precursor cells expressing developmentally downregulated protein 4 subtype 2 (Nedd4-2) and glycogen synthase kinase-3 β (GSK3β).
7 35126185 Similarly, Nedd4-2 or GSK3β overexpression resulted in increased activity of Nedd4-2 or GSK3β, and significantly downregulated nephrin levels.
8 35126185 Interestingly, ubiquitin-mediated protein degradation of nephrin was regulated by Nedd4-2, rather than by GSK3β.
9 35126185 In summary, SGK3 inactivation downregulated the levels of nephrin by increasing Nedd4-2 and GSK3β activity in ADR-induced podocyte injury model; in particular, the SGK3/Nedd4-2 signaling pathway was found to be involved in ubiquitin-mediated proteasome degradation of nephrin.
10 34780752 In fructose-exposed conditionally immortalized human podocytes, we found that atractylodin inhibited podocyte hypermotility, and up-regulated slit diaphragm proteins podocin and nephrin, and cytoskeleton protein CD2-associated protein (CD2AP), α-Actinin-4 and synaptopodin expression, which were consistent with its anti-oxidative activity evidenced by up-regulation of catalase (CAT) and superoxide dismutase (SOD) 1 expression, and reduction of reactive oxygen species (ROS) production.
11 34780752 Atractylodin also significantly suppressed expression of transient receptor potential channels 6 (TRPC6) and phosphorylated Ca2+/calmodulin-dependent protein kinase IV (CaMK4) in cultured podocytes with fructose exposure.
12 34780752 Additionally, in fructose-exposed podocytes, CaMK4 siRNA up-regulated synaptopodin and reduced podocyte hypermotility, whereas, silencing of TRPC6 by siRNA decreased p-CaMK4 expression, inhibited podocyte hypermotility, showing TRPC6/p-CaMK4 signaling activation in podocyte hypermotility under fructose condition.
13 34780752 These results first demonstrated that the anti-oxidative property of atractylodin may contribute to the suppression of podocyte hypermotility via inhibiting TRPC6/p-CaMK4 signaling and restoring synaptopodin expression abnormality.

20 33936277 Additionally, TNF-α and IL-6 secretions were elevated, and their concentrations were positively correlated with the expression of miR-155 during podocyte injury.
21 33936277 Thus, the present study indicated that miR-155 is a potential biomarker for the diagnosis of EGD, and its expression is associated with the release of pro-inflammatory cytokines and activation of mitogen-activated protein kinase (MAPK) pathway in TGF-β1-induced podocyte injury.

52 27590856 The glomerular slit diaphragm (SD) serves as a size-selective barrier and is linked to the actin-based cytoskeleton by adaptor proteins, including CD2-associated protein (CD2AP).

54 27590856 In addition, CD2AP can facilitate the nephrin-induced phosphoinositide 3-kinase (PI3-K)/Akt signaling, which protects podocytes from apoptosis.
55 27590856 Here we found that CD2AP staining was located diffusely but predominantly in the peripheral cytoplasm and CD2AP co-localized with nephrin in mouse podocytes; however, Ang II decreased CD2AP staining diffusely and induced a separation from concentrated nephrin.
56 27590856 Here we found that CD2AP staining was located diffusely but predominantly in the peripheral cytoplasm and CD2AP co-localized with nephrin in mouse podocytes; however, Ang II decreased CD2AP staining diffusely and induced a separation from concentrated nephrin.

63 27575559 Cathepsin L, a lysosomal cysteine protease, can be involved in the development of proteinuria by degradation of proteins that are important for normal podocyte architecture, such as the CD2-associated protein, synaptopodin, and dynamin.
64 27575559 Cathepsin L also activates heparanase, a heparan sulfate endoglycosidase previously shown to be crucial for the development of diabetic nephropathy.
65 27575559 In wild-type mice the early development of albuminuria correlated with the activation of heparanase and loss of heparan sulfate expression, whereas loss of synaptopodin expression and podocyte damage occurred at a later stage.
66 27575559 Most likely, cathepsin L-dependent heparanase activation is crucial for the development of albuminuria and renal damage.
67 27441654 Tankyrases, multifunctional poly(ADP-ribose) polymerase (PARP) superfamily members with features of both signaling and cytoskeletal proteins, antagonize Wnt/β-catenin signaling.
68 27441654 We found that tankyrases interact with CD2-associated protein (CD2AP), a protein essential for kidney ultrafiltration as CD2AP-knockout (CD2AP-/-) mice die of kidney failure at the age of 6-7 weeks.
69 27441654 The data revealed increased activity of β-catenin, and upregulation of lymphoid enhancer factor 1 (LEF1) (mediator of Wnt/β-catenin pathway) and fibronectin (downstream target of Wnt/β-catenin) in CD2AP-/- podocytes.
70 27441654 Total PARylation and active β-catenin were reduced in CD2AP-/- podocytes by tankyrase inhibitor XAV939 treatment.
71 27441654 However, instead of ameliorating podocyte injury, XAV939 further upregulated LEF1, failed to downregulate fibronectin and induced plasminogen activator inhibitor-1 (PAI-1) that associates with podocyte injury.
72 27441654 Collectively, the data reveal sustained activation of the Wnt/β-catenin pathway in CD2AP-/- podocytes, contributing to podocyte injury.
73 27441654 Furthermore, the data reveal that careful contemplation is required when targeting Wnt/β-catenin pathway to treat proteinuric kidney diseases associated with impaired CD2AP.

90 26546360 Lack of CD2AP disrupts Glut4 trafficking and attenuates glucose uptake in podocytes.
91 26546360 The adapter protein CD2-associated protein (CD2AP) functions in various signaling and vesicle trafficking pathways, including endosomal sorting and/or trafficking and degradation pathways.
92 26546360 Here, we investigated the role of CD2AP in insulin-dependent glucose transporter 4 (Glut4, also known as SLC2A4) trafficking and glucose uptake.
93 26546360 In subcellular membrane fractionations, CD2AP co-fractionated with Glut4, IRAP (also known as LNPEP) and sortilin, constituents of Glut4 storage vesicles (GSVs).
94 26546360 We further found that CD2AP forms a complex with GGA2, a clathrin adaptor, which sorts Glut4 to GSVs, suggesting a role for CD2AP in this process.
95 26546360 This leads to reduced insulin-stimulated trafficking of GSVs and attenuated glucose uptake into CD2AP(-/-) podocytes.
96 26296892 Differential Recognition Preferences of the Three Src Homology 3 (SH3) Domains from the Adaptor CD2-associated Protein (CD2AP) and Direct Association with Ras and Rab Interactor 3 (RIN3).
97 26296892 Thus, we studied the binding properties of each SH3 domain to the known interactor Casitas B-lineage lymphoma protein (c-CBL), conducted a peptide array screen based on the recognition motif PxPxPR and identified 40 known or novel candidate binding proteins, such as RIN3, a RAB5-activating guanine nucleotide exchange factor.
98 26296892 CD2AP SH3 domains 1 and 2 generally bound with similar characteristics and specificities, whereas the SH3-3 domain bound more weakly to most peptide ligands tested yet recognized an unusually extended sequence in ALG-2-interacting protein X (ALIX).
99 26296892 RIN3 peptide scanning arrays revealed two CD2AP binding sites, recognized by all three SH3 domains, but SH3-3 appeared non-functional in precipitation experiments.
100 26296892 RIN3 recruited CD2AP to RAB5a-positive early endosomes via these interaction sites.
101 26296892 Two high-resolution crystal structures (1.65 and 1.11 Å) of CD2AP SH3-1 and SH3-2 solved in complex with RIN3 epitopes 1 and 2, respectively, indicated that another extended motif is relevant in epitope 2.
102 26296892 In conclusion, we have discovered novel interaction candidates for CD2AP and characterized subtle yet significant differences in the recognition preferences of its three SH3 domains for c-CBL, ALIX, and RIN3.
103 26234796 Role of the heme oxygenase-adiponectin-atrial natriuretic peptide axis in renal function.
104 26234796 The mechanisms underlying the HO-mediated reno-protection include: (i) the restoration of renal morphology by enhancing proteins of regeneration, (ii) the potentiation of the HO-adiponectin-atrial natriuretic peptide axis, with corresponding suppression of oxidative/inflammatory insults and extracellular matrix/profibrotic factors, and (iii) the potentiation of podocyte cytoskeletal proteins such as nephrin, podocin, podocalyxin and CD2-associated-protein, which are fundamental for forming the glomerular filtration barrier that selectively allows small molecules to pass through but not large protein molecules.
105 26234796 Thus, this review highlights the HO-adiponectin-atrial natriuretic peptide axis in renoprotection.
106 26082520 The adaptor protein CD2BP2, originally identified as a binding partner of the adhesion molecule CD2, is a pre-spliceosomal assembly factor that utilizes its glycine-tyrosine-phenylalanine (GYF) domain to co-localize with spliceosomal proteins.
107 26082520 At the molecular level, we identified the phosphatase PP1 to be recruited to the spliceosome via the N-terminus of CD2BP2.
108 26082520 Given the strong expression of CD2BP2 in podocytes of the kidney, we use selective depletion of CD2BP2, in combination with next-generation sequencing, to monitor changes in exon usage of genes critical for podocyte functions, including VEGF and actin regulators.
109 25460740 Moreover, the effects of the HO-system on podocyte cytoskeletal proteins like podocin, podocalyxin, CD2-associated-protein (CD2AP) and proteins of regeneration/repair like beta-catenin, Oct3/4, WT1 and Pax2 in renal tissue from normoglycemic obese Zucker-fatty rats (ZFs) have not been reported.
110 25460740 These were associated with enhanced expression of beta-catenin, Oct3/4, WT1, Pax2 and nephrin, an essential transmembrane protein required for the formation of the scaffoldings of the podocyte slit-diaphragm, permitting the filtration of small ions, but not massive excretion of proteins, hence proteinuria.
111 25460740 Besides nephrin, hemin also enhanced other important podocyte-regulators including, podocalyxin, podocin and CD2AP.
112 25460740 Collectively, these data suggest that hemin ameliorates nephropathy by potentiating the expression of proteins of repair/regeneration, abating oxidative/inflammatory mediators, reducing renal histo-pathological lesions, while enhancing nephrin, podocin, podocalyxin, CD2AP and creatinine clearance, with corresponding reduction of albuminuria/proteinuria suggesting improved renal function in hemin-treated ZFs.
113 25332898 After then, CD2 associated protein, NEPH1 and transient receptor potential-6 were also found as crucial molecules of the slit diaphragm.
114 25332898 Then we have found that synaptic vesicle protein 2B, ephrin-B1 and neurexin were already downregulated at the early stage of puromycin aminonucleoside nephropathy, and that these molecules were localized close to nephrin.

122 24511139 CD2-associated protein (CD2AP) is a multidomain scaffolding protein that has a critical role in renal function.
123 24425877 CD2-associated protein (CD2AP) enhances casitas B lineage lymphoma-3/c (Cbl-3/c)-mediated Ret isoform-specific ubiquitination and degradation via its amino-terminal Src homology 3 domains.
124 24425877 In sympathetic neurons, Ret degradation is induced, at least in part, by a complex consisting of the adaptor protein CD2AP and the E3-ligase Cbl-3/c.
125 24425877 Knockdown of Cbl-3/c using siRNA reduced the GDNF-induced ubiquitination and degradation of Ret51 in neurons and podocytes, suggesting that Cbl-3/c was a predominant E3 ligase for Ret.
126 24425877 Coexpression of CD2AP with Cbl-3/c augmented the ubiquitination of Ret51 as compared with the expression of Cbl-3/c alone.
127 24425877 Ret51 ubiquitination by the CD2AP·Cbl-3/c complex required a functional ring finger and TKB domain in Cbl-3/c.
128 24425877 The SH3 domains of CD2AP were sufficient to drive the Cbl-3/c-dependent ubiquitination of Ret51, whereas the carboxyl-terminal coiled-coil domain of CD2AP was dispensable.
129 24425877 Interestingly, activated Ret induced the degradation of CD2AP, but not Cbl-3/c, suggesting a potential inhibitory feedback mechanism.
130 24425877 Taken together, these results suggest that only the SH3 domains of CD2AP were necessary to enhance the E3 ligase activity of Cbl-3/c toward Ret51.
131 24175259 These adaptor proteins, such as CD2-associated protein, zonula occludens 1, β-catenin, Nck and p130Cas, located at the intracellular SD insertion area near lipid rafts, have important structural and functional roles.
132 23681557 CD2-associated protein (CD2AP) is essential for podocyte function.
133 23555556 In both in vivo and in vitro studies, the expression of synaptopodin, a molecular marker for podocyte integrity, and the slit diaphragm constituting molecules (SDCM), such as nephrin, podocin, and CD2-associated protein (CD2AP), were decreased in morphine-treated podocytes.
134 23555556 In addition, AKT, p38, and JNK pathways were involved in morphine-induced down regulation of SDCM in human podocytes.
135 23296190 In addition to these receptors, Toll-like receptor 3 (TLR3) and retinoic acid-inducible gene 1 (RIG-I)-like helicases (RLHs), podocytes express the collateral proteins required to support intracellular signaling.
136 23296190 The transcription factor interferon regulatory factor 3 (IRF3) and nuclear factor kappa B (NF-ĸB) are phosphorylated and translocate to the nucleus, and dsRNA increases synthesis of proteins driven by IRF3 (P54, P56 and P60) or NF-ĸB (interleukin 8 and A20).
137 23296190 Furthermore, dsRNA suppresses podocyte cell migration, alters the expression of a panel of podocyte essential proteins (nephrin, podocin and CD2-associated protein or CD2AP) and changes transepithelial albumin flux.
138 22693670 The close relationships of slit diaphragm (SD) molecules such as nephrin, podocin, CD2-associated protein (CD2AP), a-actinin-4, transient receptor potential cation channel 6 (TRPC6), Densin and membrane-associated guanylate kinase inverted 1 (MAGI-1), α3β1 integrin, WT1, phospholipase C epsilon-1 (PLCE1), Lmx1b, and MYH9, and mitochondrial disorders and circulating factors in the pathogenesis of glomerular proteinuria were also gradually discovered.
139 21911934 Podocyte injury results in proteinuric kidney disease, and genetic deletion of SD-associated CD2-associated protein (CD2AP) leads to progressive renal failure in mice and humans.
140 21911934 Here, we have shown that CD2AP regulates the TGF-β1-dependent translocation of dendrin from the SD to the nucleus.
141 21911934 Nuclear dendrin acted as a transcription factor to promote expression of cytosolic cathepsin L (CatL).
142 21911934 CatL proteolyzed the regulatory GTPase dynamin and the actin-associated adapter synaptopodin, leading to a reorganization of the podocyte microfilament system and consequent proteinuria.
143 21911934 CD2AP itself was proteolyzed by CatL, promoting sustained expression of the protease during podocyte injury, and in turn increasing the apoptotic susceptibility of podocytes to TGF-β1.
144 21911934 Our study identifies CD2AP as the gatekeeper of the podocyte TGF-β response through its regulation of CatL expression and defines a molecular mechanism underlying proteinuric kidney disease.

150 21799297 Likewise, LPS treatment led to a significant decrease in CD2AP, an anchorage between podocin and F-actin.

152 21799297 Interestingly, glomerular tensin2 expression levels were also decreased during the albuminuric phase, associated with losses of glomerular F-actin and synaptopodin under septic states.

154 21799297 Based on these data, we emphasize the importance of concomitant decreases in podocin, CD2AP and tensin2 during septic ARF-associated proteinuria.

167 20654688 Lipid phosphatase SHIP2 downregulates insulin signalling in podocytes.
168 20654688 To study the role of CD2-associated protein (CD2AP) in podocyte injury, we performed a yeast two-hybrid screening on a glomerular library, and found that CD2AP bound to SH2-domain-containing inositol polyphosphate 5-phosphatase 2 (SHIP2), a negative regulator of insulin signalling.
169 20654688 SHIP2 interacts with CD2AP in glomeruli and is expressed in podocytes, where it translocates to plasma membrane after insulin stimulation.
170 20654688 Overexpression of SHIP2 in cultured podocytes reduces Akt activation in response to insulin, and promotes apoptosis.
171 20654688 SHIP2 is upregulated in glomeruli of insulin resistant obese Zucker rats.
172 20654688 These results indicate that SHIP2 downregulates insulin signalling in podocytes.
173 19679673 TGF-beta promotes proapoptotic signaling mediated by Smad3 but also activates prosurvival pathways such as phosphoinositide-3 kinase (PI3K)/AKT; the latter requires the CD2-associated adaptor protein (CD2AP) in podocytes.
174 19679673 Here, we report that CD2AP-dependent early activation of the antiapoptotic PI3K/AKT pathway does not require TGF-beta receptor-regulated Smad2 and Smad3.
175 19679673 We found that the C-terminal region of CD2AP interacts directly with the cytoplasmic tail of the TGF-beta receptor type I (TbetaRI) in a kinase-dependent manner and that the interaction between the TbetaRI and the p85 subunit of PI3K requires CD2AP.
176 19679673 Consistent with the proapoptotic function of Smad signaling, Smad2/3-deficient podocytes were hyperproliferative and resistant to TGF-beta-induced growth inhibition and apoptosis.
177 19679673 In contrast, CD2AP-deficient cells were hypoproliferative and hypersensitive to TGF-beta-induced apoptosis.
178 19679673 In vivo, to determine the effects of reduced Smad3 or CD2AP gene dosage on podocyte apoptosis and proteinuria characteristic of TGF-beta1 transgenic mice, we generated TGF-beta1 transgenic mice deficient for Smad3 or heterozygous for CD2AP.
179 19679673 Smad3 deficiency ameliorated podocyte apoptosis, and CD2AP heterozygosity increased both podocyte apoptosis and proteinuria.
180 19679673 These data define distinct canonical (Smad) and noncanonical (CD2AP/PI3K/AKT) pathways that arise from direct, independent interactions with the TbetaRI and that mediate opposing signals for podocyte death or survival.
181 19306938 Downregulation of CD2-associated protein impaired the physiological functions of podocytes.
182 19306938 Downregulation of CD2-associated protein impaired the physiological functions of podocytes.

184 19306938 Emerging evidences show that CD2-associated protein (CD2AP) is involved in podocyte injury and the pathogenesis of proteinuria.
185 19306938 These data suggest that CD2AP may play a crucial role in maintaining the normal function of podocytes and lowered CD2AP causes podocyte injury by disrupting the cytoskeleton and disturbing the nephrin-CD2AP signaling pathway.
186 19306938 These data suggest that CD2AP may play a crucial role in maintaining the normal function of podocytes and lowered CD2AP causes podocyte injury by disrupting the cytoskeleton and disturbing the nephrin-CD2AP signaling pathway.
187 19266252 Some recent studies demonstrated that podocin, CD2-associated protein and NEPH1 are also functional molecules in the slit diaphragm, and their expressions are altered in membranous nephropathy and also in focal glomerulosclerosis.
188 18753381 CD2AP and Cbl-3/Cbl-c constitute a critical checkpoint in the regulation of ret signal transduction.
189 18753381 In an effort to elucidate mechanisms that control the half-life of Ret, we have identified two novel Ret interactors, CD2-associated protein (CD2AP) and Cbl-3.
190 18753381 After Ret activation by GDNF, CD2AP dissociates.
191 18753381 In contrast to their dissociation from autophosphorylated Ret, an interaction between CD2AP and Cbl-3 is induced by GDNF stimulation of sympathetic neurons, suggesting that CD2AP and Cbl-3 dissociate from Ret as a complex.
192 18753381 In neurons, the overexpression of CD2AP enhances the degradation of Ret and inhibits GDNF-dependent survival, and gene silencing of CD2AP blocks Ret degradation and promotes GDNF-mediated survival.
193 18753381 In combination with CD2AP, however, Cbl-3 promotes Ret degradation rapidly and almost completely blocks survival promotion by GDNF, suggesting that Cbl-3 acts as a switch that is triggered by CD2AP and oscillates between inhibition and promotion of Ret degradation.
194 18753381 Consistent with the hypothesis, Cbl-3 silencing in neurons only inhibited Ret degradation and enhanced neuronal survival in combination with CD2AP silencing.
195 18753381 CD2AP and Cbl-3, therefore, constitute a checkpoint that controls the extent of Ret downregulation and, thereby, the sensitivity of neurons to GFLs.

214 18075495 Here, we show that exogenous semaphorin3a caused acute nephrotic range proteinuria associated with podocyte foot process effacement and fusion, endothelial cell damage, decreased vascular endothelial growth factor-A receptor expression, and downregulation of the slit-diaphragm proteins podocin, nephrin, and CD2-associated protein.
215 18075495 When vascular endothelial growth factor 165 was administered at the same time as Semaphorin3a, no proteinuria or renal ultrastructural abnormalities occurred, suggesting that semaphorin3a effects may be mediated, in part, by downregulation of vascular endothelial growth factor receptor 2 signaling.
216 17766183 The intracellular domain of nephrin is associated with linker proteins, such as CD2-associated protein and Nck proteins that can connect nephrin to the actin cytoskeleton.
217 17699558 In addition, after knockdown of CD2-associated protein (CD2AP) and podocin, two well-characterized genetic contributors to podocyte differentiation in mammals, we observed glomerular loss of serum macromolecules similar to that seen in mammalian kidneys with inborn mutations in these genes.

233 17537921 Nuclear relocation of the nephrin and CD2AP-binding protein dendrin promotes apoptosis of podocytes.
234 17537921 Another SD protein, CD2-associated protein (CD2AP), is an adaptor molecule involved in podocyte homeostasis that can repress proapoptotic TGF-beta signaling in podocytes.
235 17537921 Here we show that dendrin, a protein originally identified in telencephalic dendrites, is a constituent of the SD complex, where it directly binds to nephrin and CD2AP.
236 17459670 TRPC6 and FSGS: the latest TRP channelopathy.
237 17459670 Resultant to these pursuits, several podocyte structural proteins such as nephrin, podocin, alpha-actinin 4 (ACTN4), and CD2-associated protein (CD2AP) have emerged to provide critical insight into the pathogenesis of hereditary nephrotic syndromes.
238 17459670 The latest advance in familial FSGS has been the discovery of a mutant form of canonical transient receptor potential cation channel 6 (TRPC6), which causes an increase in calcium transients and essentially a gain of function in this cation channel located on the podocyte cell membrane.
239 17459670 TRPC6 channels have been shown to be activated via phospholipase C stimulation.
240 17459670 Mutant TRPC6 may also amplify injurious signals mediated by Ang II, a common final pathway of podocyte apoptosis in various mammalian species.
241 17459670 Current evidence also suggests that blocking TRPC6 channels may be of therapeutic benefit in idiopathic FSGS, a disease with a generally poor prognosis.
242 17459670 This creates the exciting possibility that blocking TRPC6 channels within the podocyte may translate into long-lasting clinical benefits in patients with FSGS.
243 17213204 CD2AP/CIN85 balance determines receptor tyrosine kinase signaling response in podocytes.
244 17213204 CD2-associated protein (CD2AP) is highly expressed in podocytes and is considered to play an important role in the maintenance of the glomerular slit diaphragm.
245 17213204 In addition, we demonstrate that CIN85, a paralog of CD2AP, is involved in termination of RTK signaling in podocytes.
246 17213204 CIN85 protein expression is increased in CD2AP(-/-) podocytes in vitro.
247 17213204 Stimulation of CD2AP(-/-) podocytes with various growth factors, including insulin-like growth factor 1, vascular endothelial growth factor, and fibroblast growth factor, resulted in a significantly decreased phosphatidylinositol 3-kinase/AKT and ERK signaling response.
248 17213204 Moreover, increased CIN85 protein is detectable in podocytes in diseased CD2AP(-/-) mice, leading to decreased base-line activation of ERK and decreased phosphorylation after growth factor stimulation in vivo.
249 17213204 Because repression of CIN85 protein leads to a restored RTK signaling response, our results support an important role of CD2AP/CIN85 protein balance in the normal signaling response of podocytes.
250 16889564 Nephrin and podocin were identified as gene products mutated in Finnish-type congenital nephrotic syndrome and autosomal recessive steroid-resistant nephrotic syndrome, respectively.
251 16889564 The expression of nephrin and podocin was reduced in glomeruli of minimal change nephrotic syndrome, which suggested that the altered expression of these molecules contributes to the development of proteinuria also in acquired diseases.
252 16889564 Some recent studies demonstrated that CD2-associated protein (CD2AP) is also a functional molecule in the slit diaphragm, and its expression is altered in membranous nephropathy.
253 16886065 Increased ferritin permeability was not observed in nephrotic CD2-associated protein-null (Cd2ap-/-) mice, which have a primary podocyte defect.
254 16841182 Podocyte-associated proteins FAT, alpha-actinin-4 and filtrin are expressed in Langerhans islets of the pancreas.
255 16841182 Recently, genetic mapping of proteinuric kidney disease genes and animal models have revealed further important molecules for the kidney filtration function including alpha-actinin-4, podocin, FAT, and NEPH1.
256 16841182 This study was addressed to explore the pancreatic expression of the podocyte molecules podocin, FAT, alpha-actinin-4, NEPH1, NEPH2, filtrin/NEPH3, synaptopodin and CD2 associated protein (CD2AP).
257 16841182 Of the nephrin-associated podocyte proteins, filtrin/NEPH3, FAT, and alpha-actinin-4 were found to be expressed in the pancreas at the gene and protein level and localized to Langerhans islets.
258 16752799 Seven genes have been recognized till present, which mutations are responsible for severe forms of NS: NPHS1, NPHS2, ACTN4, CD2AP and WT1, TRPC6, LAMB2.
259 16752799 Proteins encoded by these genes (nephrin, podocin, alpha-actinin-4, an adapter protein anchoring CD2 and others) influence the function of the podocytes.
260 16752799 It was concluded that patients with steroid resistant nephrotic syndrome (SRNS) with homozygous or compound heterozygous mutations in NPHS2 have reduced risk for recurrence of focal segmental glomerulosclerosis (FSGS) in renal transplant (only 8% in comparison with 35% in patients without mutation in NPHS2).
261 16752799 This polymorphism appears to enhance susceptibility to FSGS in association with a second mutant NPHS2 allele.
262 16752799 There are also 3 genetic loci connected with autosomal dominant forms of FSGS: ACTN4, TRPC6 and CD2AP (found only in the mice models).
263 16628251 Defects in several podocyte proteins have been implicated in the etiology of FSGS, including podocin, alpha-actinin-4, CD2-associated protein (CD2AP), and TRPC6.
264 16628251 Combinations of Cd2ap heterozygosity and heterozygosity of either synaptopodin (Synpo) or Fyn proto-oncogene (Fyn) but not kin of IRRE like 1 (Neph1) resulted in spontaneous proteinuria and in FSGS-like glomerular damage.
265 16628251 These genetic interactions were also reflected at a functional level, as we found that CD2AP associates with Fyn and Synpo but not with Neph1.
266 16541019 Sema 3A decreased semaphorin 3B, plexin A1, A3, and D1 >/=50% and reduced plexin A2 mRNA to undetectable levels.

268 16541019 Sema 3A induced a 10-fold increase in podocyte apoptosis and significantly decreased the activity of the Akt survival pathway.

272 16388393 Mice lacking CD2-associated protein (CD2AP-/-) develop glomerular lesions resembling human focal segmental glomerulosclerosis (FSGS) between 3-4 weeks of age and die approximately 2 weeks later from massive proteinuria and renal failure.
273 16280470 In the case of the podocyte line, differentiation occurred on all three matrices as indicated by the expression of synaptopodin and CD2-associated protein (CD2AP) and organization of myosin heavy chain IIA into a linear pattern.
274 16280470 Evidence for podocytic differentiation occurred on all three collagen matrices as indicated by the redistribution of myosin IIA to a linear pattern and expression of synaptopodin, CD2AP, and alpha-actinin.
275 16050398 Other genes involved in the slit-diaphragm or the nephrotic syndrome are CD2-associated protein (CD2AP), FAT1, WT1, LMX1B, SMARCAL1.
276 15997642 The main components of the slit diaphragm are nephrin, the product of NPHS1 gene and podocin, the product of NPHS2 gene.
277 15997642 Mutations in NPHS1 lead to congenital nephrotic syndrome of the Finnish type (CNF), whereas NPHS2 mutations result in focal segmental glomerulosclerosis (FSGS).
278 15997642 Reduced expression and redistribution of nephrin and podocin are also seen in podocytes of patients with acquired glomerulopathies.
279 15997642 Together with podocin and CD2AP (CD2-associated protein), nephrin forms a complex determining the integrity of the slit diaphragm.
280 15968559 Also, the genes encoding the four major slit diaphragm proteins, nephrin, podocin, Neph1 and CD2-associated protein were sequenced in 38 patients with MCNS of varying severity.
281 15968559 The genetic analyses revealed heterozygous amino acid changes in nephrin and podocin in 10 of the 38 patients studied.
282 15968559 On the other hand, the genes coding for Neph1 and CD2AP were highly conserved and no amino acid substitutions were detected.
283 15956777 The docking protein CD2AP (CD2-associated protein) serves a nonredundant function in podocytes as CD2AP knockout mice die of renal failure at the age of 6-7 wk.

319 12874460 Protein levels of nephrin, podocin, CD2-associated protein, and podocalyxin were investigated using quantitative immunohistochemical assays.

321 12874460 In most acquired renal diseases, except in IgA nephropathy, a marked reduction was observed at the protein levels of nephrin, podocin, and podocalyxin, whereas an increase of the glomerular mRNA levels of nephrin, podocin, and podoplanin was found, compared with controls.
322 12874460 The mean width of the podocyte foot processes was inversely correlated with the protein levels of nephrin (r = -0.443, P < 0.05), whereas it was positively correlated with podoplanin mRNA levels (r = 0.468, P < 0.05) and proteinuria (r = 0.585, P = 0.001).
323 12832477 Nephrin and CD2AP associate with phosphoinositide 3-OH kinase and stimulate AKT-dependent signaling.
324 12832477 Mutations of NPHS1 or NPHS2, the genes encoding nephrin and podocin, as well as the targeted disruption of CD2-associated protein (CD2AP), lead to heavy proteinuria, suggesting that all three proteins are essential for the integrity of glomerular podocytes, the visceral glomerular epithelial cells of the kidney.
325 12832477 We demonstrate that both nephrin and CD2AP interact with the p85 regulatory subunit of phosphoinositide 3-OH kinase (PI3K) in vivo, recruit PI3K to the plasma membrane, and, together with podocin, stimulate PI3K-dependent AKT signaling in podocytes.
326 12832477 Using two-dimensional gel analysis in combination with a phosphoserine-specific antiserum, we demonstrate that the nephrin-induced AKT mediates phosphorylation of several target proteins in podocytes.
327 12832477 One such target is Bad; its phosphorylation and inactivation by 14-3-3 protects podocytes against detachment-induced cell death, suggesting that the nephrin-CD2AP-mediated AKT activity can regulate complex biological programs.

334 12039988 The immunohistochemical staining showed also that the interaction partner of nephrin, CD2-associated protein (CD2AP), and the slit-diaphragm-associated protein, ZO-1alpha (-), appeared unchanged, whereas the major anionic apical membrane protein of podocytes, podocalyxin, somewhat punctate as compared with the wild-type (wt) and nephrin(wt/trap) stainings.
335 11912254 In contrast, the intensity of staining for ZO-1 and CD2-associated protein (CD2AP), two other proteins that are located on the cytoplasmic face of the slit diaphragm, was undiminished.

337 11880318 CD2-associated protein (CD2AP) is also necessary for normal glomerular permeability and is a putative nephrin adapter molecule.
338 11880318 Here, we document that nephrin and CD2AP are linked to the actin cytoskeleton.
339 11880318 As detected by Western blot analysis, nephrin and CD2AP were both insoluble when cell membranes from normal rat glomeruli were extracted with 0.5% Triton X-100 (TX-100) at 4 degrees C in the presence of divalent cations, but they were solubilized when the extraction included potassium iodide (KI) to depolymerize F-actin.
340 11880318 In addition, a small fraction of the solubilized nephrin and CD2AP was recovered in the low-density fractions of OptiPrep flotation gradients, which indicates that a portion of nephrin, possibly associated with CD2AP, resides in a cholesterol- or sphingolipid-rich region of the plasma membrane.
341 11880318 Immunofluorescent staining of unfixed sections of normal rat kidney for nephrin, CD2AP, and F-actin was unaltered by treatment with TX-100 but was greatly diminished by addition of KI.
342 11880318 These results document that nephrin anchors the slit diaphragm to the actin cytoskeleton, possibly by linkage to CD2AP, and that nephrin traverses a relatively cholesterol-poor region of the podocyte plasma membrane.
343 11880318 In addition, a small pool of actin-associated nephrin and CD2AP resides in lipid rafts, possibly in the cholesterol-rich apical region of the podocyte-foot processes.
