Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) 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). PHENOTYPE: Mice homozygous for a null allele exhibit total loss of neurotransmitter secretion from synaptic vesicles throughout development and massive neuron apoptosis after initial synaptogenesis, leading to widespread neurodegeneration and complete neonatal lethality.
