Snapin - SNAP-associated protein

Predicted to enable SNARE binding activity. Involved in anterograde synaptic vesicle transport; negative regulation of neuron projection development; and regulation of synaptic vesicle exocytosis. Acts upstream of or within several processes, including lysosomal lumen acidification; terminal button organization; and vesicle organization. Located in acrosomal vesicle; cytosol; and manchette. Part of BLOC-1 complex. Is expressed in several structures, including alimentary system; brain; cardiovascular system; genitourinary system; and immune system. Orthologous to human SNAPIN (SNAP associated protein). [provided by Alliance of Genome Resources, Apr 2022]
