Involved in several processes, including positive regulation of secretion by cell; positive regulation of vesicle docking; and regulation of protein-containing complex assembly. Acts upstream of or within protein stabilization. Located in several cellular components, including perinuclear region of cytoplasm; postsynapse; and presynapse. Part of protein-containing complex. Human ortholog(s) of this gene implicated in West syndrome and developmental and epileptic encephalopathy 4. Orthologous to human STXBP1 (syntaxin binding protein 1).

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.
