Predicted to be involved in Arp2/3 complex-mediated actin nucleation and regulation of actin filament polymerization. Predicted to be located in actin cytoskeleton. Predicted to be part of Arp2/3 protein complex. Is an ortholog of C. elegans C46H11.3;
arx-7; and
smo-1. In C. elegans,
smo-1 is involved in several processes, including chromosome organization; multicellular organismal locomotion; and muscle cell cellular homeostasis.
