Predicted to enable SH3 domain binding activity and profilin binding activity. Acts upstream of or within actin cytoskeleton organization; axon guidance; and neural tube closure. Located in filopodium; focal adhesion; and lamellipodium. Is expressed in several structures, including brain and hemolymphoid system gland. Orthologous to human VASP (vasodilator stimulated phosphoprotein). [provided by Alliance of Genome Resources, Apr 2022]
