IHC-P 1/50 - 1/100. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.


  • Function
    Potentially involved in docking of synaptic vesicles at presynaptic active zones. May play a critical role in neurotransmitter exocytosis. May mediate Ca(2+)-regulation of exocytosis acrosomal reaction in sperm.
  • Tissue specificity
    Isoform 1 is highly expressed in embryonic spinal chord and ganglia and in adult cerebellum and cerebral cortex. Isoform 2 is expressed in heart, liver, fat, skeletal muscle, kidney and brain.
  • Involvement in disease
    Note=STX1A is located in the Williams-Beuren syndrome (WBS) critical region. WBS results from a hemizygous deletion of several genes on chromosome 7q11.23, thought to arise as a consequence of unequal crossing over between highly homologous low-copy repeat sequences flanking the deleted region.
  • Sequence similarities
    Belongs to the syntaxin family.
    Contains 1 t-SNARE coiled-coil homology domain.
  • Cellular localization
    Secreted and Cytoplasmic vesicle > secretory vesicle > synaptic vesicle membrane. Cell junction > synapse > synaptosome.

Thank you very much for your interest in ab103179. The immunogenic region (amino acids 36 - 65 of Human Syntaxin 1a) shows 100% homology with the Mouse Syntaxin 1a. Because we carry over 70,000 products, it isn't feasible for us to keep small sampl...
