产品详细信息
PEP-021 is a 15 amino acid (amino acids 352-366) synthetic peptide whose sequence is found in rat and human PSD-93. The sequence of this peptide is (amino to carboxy terminus): N352-K-L-C-D-K-P-A-S-P-R-H-Y-S-P366
This peptide may be used for neutralization and control experiments with the polyclonal antibody that reacts with this product and PSD-93, catalog # PA1-043. 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.
靶标信息
PSD-93, also known as chapsyn-110, is one of a family of plasma membrane-associated proteins found in synaptic junctions. PSD-93 is unique among family members in its expression in Purkinje neuron cell bodies and dendrites. PSD-93 has three ~90 amino acid repeats called PDZ domains, a single interior SH3 domain, and a carboxyl-terminal guanylate kinase homology (GuK) domain that is enzymatically inactive. It is hypothesized that PDZ-domain interactions play a role in receptor and channel clustering which contributes to neuronal plasticiyt. PSD-93 is believed to participate in the clustering of certain proteins, including NMDA receptors and shaker-type potassium channels at the synaptic membrane. There are two principal modes of interaction between PSD-93 and other proteins. 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 may interact with PSD-93 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 PSD-93 in vitro through a pseudo-homotypic PDZ-PDZ interaction.
