Predicted to enable DNA binding activity; GTPase activator activity; and metal ion binding activity. Predicted to be involved in regulation of catalytic activity. Predicted to act upstream of or within acrosome assembly; intermediate filament organization; and spermatid nucleus differentiation. Predicted to be located in cell projection; intracellular membrane-bounded organelle; and neuronal cell body. Predicted to be active in cytoplasmic vesicle. Orthologous to human AGFG1 (ArfGAP with FG repeats 1). [provided by Alliance of Genome Resources, Apr 2022]
