Predicted to enable GTPase activator activity; SH3 domain binding activity; and phospholipid binding activity. Predicted to be involved in cilium assembly; positive regulation of membrane tubulation; and positive regulation of podosome assembly. Predicted to act upstream of or within negative regulation of dendritic spine development. Predicted to be located in dendritic spine. Predicted to be active in cell projection membrane; cytosol; and podosome. Orthologous to human ASAP1 (ArfGAP with SH3 domain, ankyrin repeat and PH domain 1).
