Species enclosed in parentheses are predicted to react based on 100% sequence homology. Species cross-reactivity is determined by Western blot.
Specificity / Sensitivity
PSD95 Antibody detects endogenous levels of total PSD95 protein.
Source / Purification
Polyclonal antibodies are produced by immunizing rabbits with a synthetic peptide (KLH-coupled) corresponding to residues 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 N-terminal variable segment followed by three PDZ domains, a SH3 domain and an inactive guanylate kinase (GK) domain. PSD95 is a scaffolding protein and is 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). The protein is implicated in experience dependent plasticity and plays an indispensable role in learning (4). Mutations in PSD95 are associated with autism (5).
