ARX-3

CELE_Y79H2A.6, Y79H2A.6
arx-3 also called as p41Arc encodes a subunit of the actin related protein of the conserved Arp2/3 complex, with 60% amino acid similarity with the homologous genes from human (OMIM: 604223); arx-3 is an essential gene as disruption in the expression by RNAi results in embryonic arrest due to ventral enclosure during morphogenesis; Arp2/3 depletion results in partial shrinking of the Ea/p apical surfaces and incomplete Ea/p cell internalization; WSP-1 activates Arp2/3 complex in vitro; WSP-1 and the Arp2/3 complex associate and function cell autonomously at cell boundaries during ventral enclosure; localization of WSP-1 is dependent on the Arp2/3 complex; expression of WSP-1 increases by the reduction of functional ARX-1. Arp2/3 regulates some Apical Junction components in embryos and adults; Arp2/3 is required during intestinal morphogenesis for regulation of intestinal lumen width in embryos and apical F-actin accumulation during larval and adult growth.
