The PHD/LAP-domain protein M153R of myxomavirus is a ubiquitin ligase that induces the rapid internalization and lysosomal destruction of CD4.
|
2 |
12502858
|
Surface expression of CD4 was restored upon overexpression of Hrs, a ubiquitin interaction motif-containing protein that sorts ubiquitinated proteins into endosomes.
|

12502858
|
Moreover, the purified PHD/LAP zinc finger of M153R catalyzed the formation of multiubiquitin adducts in vitro.

|
The poxviral RING protein p28 is a ubiquitin ligase that targets ubiquitin to viral replication factories.
|
5 |
15596852
|
Furthermore, p28 is ubiquitinated in vivo and ubiquitin colocalizes with p28 to virus factories independently of an intact RING domain.

In endothelial cells (ECs), K5 additionally reduced expression of CD31/platelet-endothelial cell adhesion molecule (PECAM), an adhesion molecule regulating cell-cell interactions of ECs, platelets, monocytes, and T cells.
|

|
In the endoplasmic reticulum, newly synthesized CD31 was degraded by proteasomes, which required binding of phosphofurin acidic cluster sorting protein-2 (PACS-2) to acidic residues in the carboxyterminal tail of K5.
|
8 |

|
Thus, CD31, a novel target of K5, is efficiently removed from ECs by a dual degradation mechanism that is regulated by the subcellular sorting of the ubiquitin ligase.

Respiratory syncytial virus NS1 protein degrades STAT2 by using the Elongin-Cullin E3 ligase.
|
10 |
17251292
|
Degradation of STAT2 requires proteasomal activity and is dependent on the expression of RSV NS1 and NS2 (NS1/2).
|
11 |
17251292
|
Here we investigate whether RSV NS proteins can assemble ubiquitin ligase (E3) enzymes to target STAT2 to the proteasome.
|
12 |
17251292
|
We demonstrate that NS1 contains elongin C and cullin 2 binding consensus sequences and can interact with elongin C and cullin 2 in vitro; therefore, NS1 has the potential to act as an E3 ligase.
|
13 |
17251292
|
By knocking down expression of specific endogenous E3 ligase components using small interfering RNA, NS1/2, or RSV-induced STAT2, degradation is prevented.

E6 hijacks a cellular ubiquitin ligase, E6AP, resulting in the ubiquitylation and degradation of the p53 tumor suppressor, as well as several other cellular proteins.
|

|
We showed previously that 68k-ank is composed of ankyrin repeats and an F-box-like domain and forms an SCF ubiquitin ligase complex together with the cellular proteins Skp1a and Cullin-1.

K3/MIR1 and K5/MIR2 of Kaposi's sarcoma-associated herpesvirus (KSHV) are viral members of the membrane-associated RING-CH (MARCH) ubiquitin ligase family and contribute to viral immune evasion by directing the conjugation of ubiquitin to immunostimulatory transmembrane proteins.
|
17 |

|
Here we establish that despite its type II transmembrane topology and carboxy-terminal glycosylphosphatidylinositol (GPI) anchor, BST2 represents a bona fide target of K5 that is downregulated during primary infection by and reactivation of KSHV.
|
18 |
19605472
|
Ubiquitination of BST2 is required for degradation, since BST2 lacking cytosolic lysines was K5 resistant and ubiquitin depletion by proteasome inhibitors restored BST2 surface expression.

WW domains from the ubiquitin ligase Nedd4 serve as an adapter to bind the antigen to Pt-Dd.

Adoptive transfer of siRNA Cblb-silenced CD8+ T lymphocytes augments tumor vaccine efficacy in a B16 melanoma model.
|
21 |

|
The ubiquitin ligase Cbl-b is an established regulator of T cell immune response thresholds.
|
22 |
22962608
|
Importantly, CBLB silencing in human CD8(+) T cells mirrored the effects observed for cblb-silenced and cblb-deficient murine T cells.

An in vitro model of antigen presentation showed that ligands for TLR-9, 7, 4 and 1/2 increased the ability of APCs to present antigen-85B of BCG to CD4 T cells, which correlated with an increase in MHC-II expression.
|
24 |
24384074
|
TLR-activation led to a down-regulation of MARCH1 ubiquitin ligase which prevents the degradation of MHC-II and decreased IL-10 also contributed to an increase in MHC-II.
|
25 |
24384074
|
TLR-activation induced up-regulation of MHC-II was inhibited by the blockade of IRAK, NF-kB, and MAPKs.
|
26 |
24384074
|
TLR-7 and TLR-9 ligands had the most effective adjuvant like effect on MHC-II of APCs which allowed BCG vaccine mediated activation of CD4 T cells.
