Clone Host Grade Applications
Polyclonal Rabbit Serum B IP
Syntaxin 1, also known as HPC-1, is a 35kD integral membrane protein which along with SNAP-25, and VAMP/synaptobrevin plays a role in vesicular trafficking and membrane fusion. Two syntaxin 1 isoforms have been identified, syntaxin 1A which is localized to nerve terminals of sensory neurons and nerve fibers reaching small blood vessels, and syntaxin 1B which is localized to motor end plates and muscle spindles. The SNARE (soluble N-ethylmaleimide sensitive fusion protein [NSF] attachment protein [SNAPs] receptors) hypothesis of membrane fusion proposes that syntaxin 1A and SNAP-25 (target membrane SNAREs, t-SNAREs) and VAMP/synaptobrevin (vesicular SNAREs, v-SNAREs) bind together to form a tripartite structure that along with soluble cytosolic proteins allows for close membrane apposition of donor and target membranes thereby facilitating membrane fusion. The interaction of syntaxin 1A with v-SNAREs is thought to be negatively regulated by the binding of munc-18 to syntaxin 1A and this interaction is controlled by Cdk5 phosphorylation of munc-18. Syntaxin 1A can be phosphorylated by casein kinase II and phosphorylation of syntaxin enhances its interaction with synaptotagmin.
