Phosphatidylinositol 4,5-bisphosphate induces actin-based movement of raft-enriched vesicles through WASP-Arp2/3

TL;DR: Overexpression of type I phosphatidylinositol phosphate 5-kinase (PIP5KI), which synthesizes PIP(2), promoted actin polymerization from membrane-bound vesicles to form motile actin comets, establishing that rafts promote comet formation.
Journal ArticleDOI

Cdc42 induces filopodia by promoting the formation of an IRSp53:Mena complex.

TL;DR: It is concluded that the interaction of Cdc42 with the partial CRIB motif of IRSp53 relieves an intramolecular, autoinhibitory interaction with the N terminus, allowing the recruitment of Mena to theIRSp53 SH3 domain.
Journal ArticleDOI

Plexin-B semaphorin receptors interact directly with active Rac and regulate the actin cytoskeleton by activating Rho

TL;DR: The findings that plexin-B signaling to the cytoskeleton is both Rac and Rho dependent form a starting point for unraveling the mechanism by which semaphorins and plexins control axon guidance and cell migration.
