Predicted to enable anion binding activity and phosphatidylinositol binding activity. Predicted to be involved in positive regulation of GTPase activity. Predicted to act upstream of or within inositol lipid-mediated signaling. Predicted to be located in membrane and mitochondrial envelope. Predicted to be active in intracellular membrane-bounded organelle and plasma membrane. Is expressed in several structures, including brain; future brain; heart; inner ear; and limb bud. Orthologous to human ADAP2 (ArfGAP with dual PH domains 2). [provided by Alliance of Genome Resources, Apr 2022]
