About Stxbp1

Summary

Enables several functions, including Enzyme binding activity; identical protein binding activity; and syntaxin-1 binding activity. 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 axon; perinuclear region of cytoplasm; and postsynapse. Part of protein-containing complex. Colocalizes with plasma membrane. Human ortholog(s) of this gene implicated in West syndrome and developmental and epileptic encephalopathy 4. Orthologous to human STXBP1 (syntaxin binding protein 1). [provided by Alliance of Genome Resources, Apr 2022]
