Application Abreviews Notes
WB 1/10000 - 1/50000. Detects a band of approximately 68 kDa (predicted molecular weight: 68 kDa).
IHC-P 1/250 - 1/500. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
ICC 1/100 - 1/250.
  • Application notesIs unsuitable for Flow Cyt or IP.
  • Target

    • FunctionMay participate in the regulation of synaptic vesicle docking and fusion, possibly through interaction with GTP-binding proteins. Essential for neurotransmission and binds syntaxin, a component of the synaptic vesicle fusion machinery probably in a 1:1 ratio. Can interact with syntaxins 1, 2, and 3 but not syntaxin 4. May play a role in determining the specificity of intracellular fusion reactions.
    • Tissue specificityBrain and spinal cord. Highly enriched in axons.
    • Involvement in diseaseDefects in STXBP1 are the cause of epileptic encephalopathy early infantile type 4 (EIEE4) [MIM:612164]. Affected individuals have neonatal or infantile onset of seizures, suppression-burst pattern on EEG, profound mental retardation, and MRI evidence of hypomyelination.
    • Sequence similaritiesBelongs to the STXBP/unc-18/SEC1 family.
    • Cellular localizationCytoplasm. Membrane.
