Stxbp1 Gene Summary [Mouse]
Enables syntaxin-1 binding activity. Involved in synaptic vesicle priming and vesicle docking involved in exocytosis. Acts upstream of or within several processes, including axon target recognition; chemical synaptic transmission; and negative regulation of synaptic transmission. Located in axon; phagocytic vesicle; and plasma membrane. Is active in several cellular components, including parallel fiber to Purkinje cell synapse; presynaptic active zone cytoplasmic component; and presynaptic cytosol. Is extrinsic component of presynaptic 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).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Stxbp1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
