General description

As a member of the membrane-associated guanylate kinase (MAGUK) family, PSD93 (also known as Chapsyn-110) binds directly to the N-methyl-D-aspartate (NMDA) receptor and the Shaker K+ channel subunits. It shares 70-80% homology with PSD-95 (SAP90), and SAP97. Like PSD-95, PSD93 plays a key role in postsynaptic targeting. Aside from binding to glutamate receptors, the MAGUK family of proteins also interacts with cell surface structures, like cell adhesion molecules, ion channels, cytoskeletal elements, and signal transduction molecules. Improper PSD93 signaling has been implicated in certain disease states, such as schizophrenia.

Specificity

This antibody does not demonstrate cross reactivity with other MAGUK family members, such as PSD-95, SAP97, and SAP102 expressed in transfected cells.

Immunogen

Recombinant protein corresponding to rat PSD93.

Application

Detect PSD93 using this Anti-PSD93 Antibody, clone N18/30 validated for use in Western Blotting & IHC.

Western Blot Analysis: 1 µg/mL from a representative lot detected PSD93 in 10 µg of human brain tissue lysate.

Immunohistochemistry Analysis: A representative lot detected PSD93 in rat brain tissue (Prof. J. Trimmer, University of California, Davis).

Western Blot Analyis: A representative lot detected PSD93 in WT, but not in PSD93 knockout mice.

Western Blot Analysis: A representative lot detected PSD93 in CA1 tissue lysates from C57BL/6 mice (Jeffrey, R. A., et al. (2009). J Neurosci. 29(50):15613-15620.).

Quality

Evaluated by Western Blot in mouse brain tissue lysate.

Western Blot Analysis: 1 µg/mL of this antibody detected PSD93 in 10 µg of mouse brain tissue lysate.

While mixed primary cerebellar cultures prepared from embryonic tissue have proven valuable for dissecting structure-function relationships in cerebellar Purkinje neurons (PNs), this technique is technically challenging and often yields few cells. Recently, mouse embryonic stem cells (mESCs) have been successfully

Postsynaptic density protein-95 (PSD-95) is a major regulator in the maturation of excitatory synapses by interacting and trafficking N-methyl-D-aspartic acid receptors (NMDAR) and α-amino-3-hydroxy-5-methyl-4-isox-azoleproprionic acid receptors (AMPAR) to the postsynaptic membrane. PSD-95 disruption has recently been associated with neuropsychiatric disorders
