Summary: 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 active in microvesicle. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system; and integumental system. Orthologous to human SNAPIN (SNAP associated protein). [provided by Alliance of Genome Resources, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
