Application Abreviews Notes
ELISA 1/5000.
WB 1/500 - 1/1000. Detects a band of approximately 33 kDa (predicted molecular weight: 33 kDa).


  • 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.
