The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
This peptide may be used for neutralization and control experiments with the polyclonal antibody that reacts with this product and Munc 18, catalog ab3451. Using a solution of peptide of equal volume and concentration to the corresponding antibody will yield a large molar excess of peptide (~ 70-fold) for competitive inhibition of antibody-protein binding reactions.

FunctionMay participate in the regulation of synaptic vesicle docking and fusion, possibly through interaction with GTP-binding proteins. Essential for neurotransmission and binds syntaxin, a component of the synaptic vesicle fusion machinery probably in a 1:1 ratio. Can interact with syntaxins 1, 2, and 3 but not syntaxin 4. May play a role in determining the specificity of intracellular fusion reactions.
Tissue specificityBrain and spinal cord. Highly enriched in axons.
Involvement in diseaseDefects in STXBP1 are the cause of epileptic encephalopathy early infantile type 4 (EIEE4) [MIM:612164]. Affected individuals have neonatal or infantile onset of seizures, suppression-burst pattern on EEG, profound mental retardation, and MRI evidence of hypomyelination.
Sequence similaritiesBelongs to the STXBP/unc-18/SEC1 family.
