Predicted to enable several functions, including GTPase activator activity; phosphatidylinositol-3,4,5-trisphosphate binding activity; and tubulin binding activity. Involved in regulation of embryonic development. Acts upstream of or within neuroblast proliferation. Predicted to be located in several cellular components, including cleavage furrow; midbody; and spindle. Predicted to be extrinsic component of cytoplasmic side of plasma membrane. Predicted to be part of centralspindlin complex. Is expressed in several structures, including blastocyst; central nervous system; early embryo; neural retina; and nose. Orthologous to human RACGAP1 (Rac GTPase activating protein 1). [provided by Alliance of Genome Resources, Apr 2022]
