Gene: Stxbp1 (syntaxin binding protein 1) Rattus norvegicus
Symbol: Stxbp1
Name: syntaxin binding protein 1
RGD ID: 3785
Description: 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 perinuclear region of cytoplasm; postsynapse; and presynapse. 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); PARTICIPATES IN insulin secretion pathway; synaptic vesicle exocytosis - neurotransmitter release pathway; INTERACTS WITH 1,3-dinitrobenzene; 2-ethoxyethanol; 2-methoxyethanol.
Type: protein-coding
RefSeq Status: VALIDATED
