PEP-280 is a 16 amino acid synthetic peptide whose sequence corresponds to residues 187-202 of rat Synaptogyrin 1. The sequence of this peptide is (amino to carboxy terminus): D (187)-P-S-Q-D-S-S-M-P-Y-A-P-Y-V-E-P (202).
This peptide may be used for neutralization and control experiments with the polyclonal antibody that reacts with this product, Synaptogyrin 1, catalog # PA1-1044. 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.

Synaptogyrins comprise a family of tyrosine-phosphorylated membrane proteins with two neuronal (SYNGR1 and SYNGR3) and one ubiquitous (SYNGR2) members. SYNGR1 and -3 are synaptic vesicle proteins, residing in some cases on the same synaptic vesicle, and are thought to be involved in the regulation of neurotransmitter release. SYNGR2, by contrast, is absent from synaptic vesicles. The role and localization of a fourth synaptogyrin, SYNGR4, is unclear. The gene for SYNGR1is located at chromosome 22q13, a region linked to schizophrenia; however, there is mixed evidence suggesting that mutations in SYNGR1 might be associated with schizophrenia.
