Product Specific Information

PEP-023 is an 18 amino acid (amino acids 83-100) synthetic peptide whose sequence is found in rat SAP102. The sequence of this peptide is (amino to carboxy terminus): G83-P-V-P-P-K-P-V-P-G-K-N-T-P-K-L-N-G100

This peptide may be used for neutralization and control experiments with the polyclonal antibody that reacts with this product and SAP102, catalog # PA1-045. Using a solution with equal weights per unit volume of peptide and corresponding antibody will yield a solution with a large molar excess of peptide that is able to competitively bind the antibody.

Reconstitute with 0.1 mL of distilled water.

Target Information

Synapse-Associated Protein 102 (SAP102) is one of a family of plasma membrane-associated proteins found in synaptic junctions. Like other members of the family, SAP102 has three approximately 90 amino acid repeats called PDZ domains followed by an SH3 domain and a yeast guanylate kinase homology (GuK) domain. It is hypothesized that PDZ-domain interactions play a role in receptor and channel clustering which contributes to neuronal plasticity. SAP102 is believed to participate in the clustering of certain proteins, including NMDA receptors, shaker-type potassium channels at the synaptic membrane in CNS neurons. NMDA receptors and Shaker-type potassium channels both share C-terminal sequence homology consisting of a threonine/serine-X-valine-COOH (T/SXV) motif. Other neuronal proteins that share this motif (beta 1 adrenergic receptor, some serotonin receptors, some sodium channel subunits, and additional potassium channel subunits) may interact with SAP102 by binding to its PDZ domains. Neuronal nitric oxide synthase (nNOS), which lacks the T/SXV motif but which has its own PDZ domain, has been shown to associate with SAP102 in vitro through a pseudo-homotypic PDZ-PDZ interaction.
