1 19052171 In podocytes, small interfering RNA knockdown of endogenous TRPC6 reduced steady-state surface expression of endogenous Slo1 channels, but knockdown of TRPC3 had no effect.
2 19052171 These data indicate that TRPC6 and TRPC3 channels can bind to Slo1, and this colocalization may allow them to serve as a source of Ca(2+) for the activation of BK(Ca) channels.
3 19403801 Partial knockdown of endogenous MAGI-1 expression by small interfering RNA (siRNA) in differentiated podocytes increased the surface expression of endogenous Slo1 as assessed by electrophysiology and cell-surface biotinylation assays, whereas overexpression of MAGI-1a reduced steady-state voltage-evoked outward current through podocyte BK(Ca) channels.
4 19794150 Here we show that Slo1 proteins interact with Neph1, a member of the immunoglobulin superfamily expressed in slit diaphragm domains of podocytes and in vertebrate and invertebrate nervous systems.
5 19794150 Neph1 can interact with all three extreme COOH-terminal variants of Slo1 (Slo1(VEDEC), Slo1(QEERL), and Slo1(EMVYR)) as ascertained by glutathione S-transferase (GST) pull-down assays and by coimmunoprecipitation.
6 19794150 Neph1 is partially colocalized in intracellular compartments with endogenous Slo1 in podocytes and ciliary ganglion neurons.
7 19794150 Consistent with this, small interfering RNA (siRNA) knockdown of endogenous Neph1 in embryonic day 10 ciliary ganglion neurons causes an increase in steady-state surface expression of Slo1 and an increase in whole cell Ca(2+)-dependent K(+) current.
8 19794150 Surprisingly, a comparable Neph1 knockdown in podocytes causes a decrease in surface expression of Slo1 and a decrease in whole cell BK(Ca) currents.
9 18480178 We detected nephrin binding to the Slo1 VEDEC splice variant, which is typically retained in intracellular stores, and to the beta4-subunit.
10 18480178 Stimulation of Slo1 VEDEC surface expression in HEK-293T cells was also observed by coexpressing a small construct encoding only the distal COOH-terminal domains of nephrin that interact with Slo1.
11 18480178 Reduction of endogenous nephrin expression by application of small interfering RNA to differentiated cells of an immortalized podocyte cell line markedly reduced the steady-state surface expression of Slo1 as assessed by electrophysiology and cell-surface biotinylation assays.
