Syntaxin is a 35kD synaptic protein capable of interacting with the synaptic vesicle protein synaptotagmin. It facilitates the docking and fusion of synaptic vesicles with the plasma membrane. Monoclonal anti-syntaxin antibody can be used to screen λ gt 11 library of rat hippocampus to isolate syntaxin cDNA clones. It can also be used in microarray and immunocytochemistry. Mouse anti-syntaxin antibody reacts specifically with membrane protein syntaxin (35 kD). The product has also shown cross reactivity for rabbit, rat and bovine but not for guinea pig.
Syntaxin 1 (STX1A) may control exocytosis in synaptic vesicles. In retina, STX1A may help in the structural formation of the inner nuclear layer (INL) and outer plexiform layer (OPL). Deletion of STX1A in mice affects the functions of hypothalamic-pituitary-adrenal axis. It may participate in spinal nociceptive plasticity promoted by peripheral nerve injury. It has been implicated in docking at synaptic vesicles of presynaptic neurotransmitter release sites.
