Involvement in disease 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.
Subcellular Location Cytoplasmic vesicle, secretory vesicle, synaptic vesicle membrane, Single-pass type IV membrane protein, Cell junction, synapse, synaptosome, Cell membrane
Protein Families Syntaxin family
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.
