Predicted to be a structural constituent of presynapse. Predicted to be involved in several processes, including dense core granule cytoskeletal transport; regulation of dendritic spine morphogenesis; and regulation of synaptic vesicle exocytosis. Is active in glutamatergic synapse and presynaptic cytosol. Is expressed in several structures, including adrenal gland; brain; pancreas; retina layer; and testis. Orthologous to human PPFIA2 (PTPRF interacting protein alpha 2). [provided by Alliance of Genome Resources, Apr 2022]
