Ca(2+)-regulated actin-binding protein. May have a unique function in the morphogenesis of neuronal cells which form ganglia. Required for SREC1-mediated regulation of neurite-like outgrowth. Plays a role in regenerative sensory axon outgrowth and remodeling processes after peripheral injury in neonates. Involved in the formation of long fine actin-containing filopodia-like structures in fibroblast. Plays a role in ciliogenesis.
Associates (via C-terminus) with actin. Interacts with F-actin (By similarity). Interacts with SCARF1; the interaction occurs in embryonic dorsal root ganglions at 18 dpc and induces neurite-like outgrowth.
