Syntaphilin is a protein selectively expressed in brain. Syntaphilin competes with SNAP-25 for binding to syntaxin-1 and inhibits SNARE complex formation by absorbing free syntaxin-1, and thereby regulates synaptic vesicle exocytosis (PMID: 10707983). The deduced 537-amino acid syntaphilin protein contains an N-terminal proline-rich domain, a predicted coiled-coil domain, a putative C-terminal transmembrane domain, and numerous consensus sites for protein phosphorylation. Whereas the calculated molecular mass of syntaphilin is 58 kDa, the apparent molecular mass of 70-75 kDa is larger than the predicted mass, suggesting a posttranslational modification of syntaphilin (PMID: 9205841; 10707983). An extra band of 65 kDa was also detected by this antibody that may represent an alternative syntaphilin gene product or a stable degradation product (PMID: 10707983; 24457644).
