CC -!- FUNCTION: Actin-binding protein that enhances membrane ruffling and RAC
CC activation. Enhances the actin-bundling activity of LCP1. Binds
CC calcium. Plays a role in RAC signaling and in phagocytosis. May play a
CC role in macrophage activation and function. Promotes the proliferation
CC of vascular smooth muscle cells and of T-lymphocytes. Enhances
CC lymphocyte migration. Plays a role in vascular inflammation.
