CST, 3919S, Phospho-PSD95 (Tyr236/Tyr240) Antibody

Polyclonal Antibody for studying PSD-95 (Tyr236/Tyr240) phosphate. Validated for Western Blotting. Highly specific and rigorously validated in-house, Phospho-PSD95 (Tyr236/Tyr240) Antibody (CST #3919) is ready to ship. Product Usage Information Western Blotting: 1:1000 Storage Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at -20°C. Do not aliquot the antibody. Protocol Available protocols: Western Blotting Specificity / Sensitivity Phospho-PSD95 (Tyr236/Tyr240) Antibody detects endogenous levels of PSD95 protein only when phosphorylated at Tyr236 or Tyr240. Species Reactivity: Rat Source / Purification Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr236 and Tyr240 of human PSD95. Antibodies are purified by protein A and peptide affinity chromatography. Background Postsynaptic Density protein 95 (PSD95) is a member of the membrane-associated guanylate kinase (MAGUK) family of proteins. These family members consist of an amino-terminal variable segment followed by three PDZ domains, an SH3 domain, and an inactive guanylate kinase (GK) domain. PSD95 is a scaffolding protein involved in the assembly and function of the postsynaptic density complex (1-2). PSD95 participates in synaptic targeting of AMPA receptors through an indirect manner involving stargazin and related transmembrane AMPA receptor regulatory proteins (TARPs) (3). It is implicated in experience-dependent plasticity and plays an indispensable role in learning (4). Mutations in PSD95 are associated with autism (5). Phospho-PSD95 (Tyr236/Tyr240) Antibody is directed against previously unpublished PSD95 tyrosine phosphorylation sites at Tyr236 and Tyr240 that were identified at Cell Signaling Technology (CST) using PhosphoScan , CST's MS/MS platform for phosphorylation site discovery. Phosphorylation of PSD95 at Tyr236 and Tyr240 was observed in extracts isolated from ischemic rat brain. The sites were independently found in a large-scale identification of tyrosine phosphorylation sites from murine brain (6).
