Is predicted to encode a protein with the following domains: Actin-related protein 2; ATPase, nucleotide binding domain; Actin; and Actin family. Is an ortholog of C. elegans
arx-2. In C. elegans,
arx-2 is involved in Arp2/3 complex-mediated actin nucleation; embryonic morphogenesis; and epithelial cell migration.
