Stxbp1 - syntaxin binding protein 1

Enables syntaxin-1 binding activity. Involved in presynaptic dense core vesicle exocytosis and synaptic vesicle priming. Acts upstream of or within several processes, including axon target recognition; chemical synaptic transmission; and negative regulation of synaptic transmission. Located in several cellular components, including glutamatergic synapse; phagocytic vesicle; and presynaptic active zone membrane. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system gland; and sensory organ. Human ortholog(s) of this gene implicated in West syndrome and developmental and epileptic encephalopathy 4. Orthologous to human STXBP1 (syntaxin binding protein 1).
