Predicted to enable GTPase activator activity. Predicted to be involved in cell migration; positive regulation of GTPase activity; and regulation of stress fiber assembly. Predicted to be located in cytosol and nucleoplasm. Predicted to be active in focal adhesion; intracellular membrane-bounded organelle; and ruffle. Orthologous to human ASAP3 (ArfGAP with SH3 domain, ankyrin repeat and PH domain 3). [provided by Alliance of Genome Resources, Apr 2022]
