Summary: Enables syntaxin binding activity. Involved in regulation of synaptic vesicle priming and synaptic vesicle priming. Acts upstream of or within several processes, including SNARE complex disassembly; apical protein localization; and nervous system development. Located in myelin sheath. Part of synaptobrevin 2-SNAP-25-syntaxin-1a complex. Is active in glutamatergic synapse. Is expressed in central nervous system; peripheral nervous system ganglion; and retina. Orthologous to human NAPA (NSF attachment protein alpha). [provided by Alliance of Genome Resources, Dec 2024]

results showed that alpha-SNAP protein is highly expressed in granulosa cells and its expression is modulated by gonadotropin stimuli.
Title: α-SNAP is expressed in mouse ovarian granulosa cells and plays a key role in folliculogenesis and female fertility.
alpha-SNAP is a crucial component of Orai1 channels, and its depletion disrupts the functional assembly of Orai1 multimers. Here the authors show that alpha-SNAP hypomorph, hydrocephalus with hopping gait, Napa(hyh/hyh) mice harbor significant defects in CD4 T cell gene expression and Foxp3 regulatory T cell (Treg) differentiation.

Furthermore, alphaSNAP-deficient mutant animals displayed reduced formation of lysozyme granules in small intestinal crypts and decreased expression of lysozyme and defensins in the intestinal mucosa, which is indicative of defects in Paneth cell differentiation. By contrast, development of Goblet cells, enteroendocrine cells, and assembly of enterocyte apical junctions was not altered in hyh mutant mice. Our data reve...

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.
