چکیده

Short Abstract – Nephrin is a transmembrane protein essential for the formation of actin-based foot processes in glomerular podocytes. Its cytosolic domain contains three tyrosine motifs which recruit Nck, a SH3-SH3SH3-SH2 protein, upon phosphorylation. SH3 domains of Nck recruit WASP to form the Nephrin/Nck/WASP signalsome by binding the poly-proline motifs in WASP [1]. The multi-valences of the components may provide the signalsome multiple copies of each player and varying stoichiometry. The presence of multiple nephrin in the signalsome may promote nephrin clustering and the oligomerization of WASP may be responsible for the integrity of the actin cytoskeleton. Here, we are investigating the hypothesis.

Stoichiometry of Nck-dependent actin polymerization in living cells

Regulation of actin dynamics through the Nck/N-WASp (neural Wiskott-Aldrich syndrome protein)/Arp2/3 pathway is essential for organogenesis, cell invasiveness, and pathogen infection. Although many of the proteins involved in this pathway are known, the detailed mechanism by which it functions remains undetermined. To examine the signaling mechanism, we used a two-pronged strategy involving com...

Nck by the numbers

A growing axon, a cancer cell on the move, and a virus spreading from cell to cell have at least one thing in common—they receive a boost from the Nck adaptor proteins that help control actin dynamics. Ditlev et al. reveal that the density and relative amounts of Nck proteins determine their effects on actin polymerization (1). By activating the N-WASp–Arp2/3 pathway, Nck proteins trigger actin...

WIP Provides an Essential Link between Nck and N-WASP during Arp2/3-Dependent Actin Polymerization

Nck links phosphotyrosine-based signaling to Arp2/3-dependent actin polymerization during many different cellular processes as well as actin-based motility of enteropathogenic Escherichia coli (EPEC), vaccinia, and other vertebrate poxviruses by interacting with N-WASP/WASP. Nck also binds WASP-interacting protein (WIP), which inhibits the ability of N-WASP to activate the Arp2/3 complex until ...

Nck proteins maintain the adult glomerular filtration barrier.

Within the glomerulus, the scaffolding protein nephrin bridges the actin-rich foot processes that extend from adjacent podocytes to form the slit diaphragm. Mutations affecting a number of slit diaphragm proteins, including nephrin, cause glomerular disease through rearrangement of the actin cytoskeleton and disruption of the filtration barrier. We recently established that the Nck family of Sr...

Nck and phosphatidylinositol 4,5-bisphosphate synergistically activate actin polymerization through the N-WASP-Arp2/3 pathway.

The Wiskott-Aldrich syndrome protein (WASP) and its relative neural WASP (N-WASP) regulate the nucleation of actin filaments through their interaction with the Arp2/3 complex and are regulated in turn by binding to GTP-bound Cdc42 and phosphatidylinositol 4,5-bisphosphate. The Nck Src homology (SH) 2/3 adaptor binds via its SH3 domains to a proline-rich region on WASP and N-WASP and has been im...
