Protocols
- 4852:
- Flow, Immunoprecipitation, Western Blotting
Specificity / Sensitivity
PCTAIRE 1 Antibody detects endogenous levels of total PCTAIRE 1.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to the sequence of human PCTAIRE 1. Antibodies are purified by protein A and peptide affinity chromatography.
Background
Three distinct PCTAIRE isoforms (PCTAIRE 1, PCTAIRE 2 and PCTAIRE 3) have been identified in humans and belong to the CDK family of serine/threonine protein kinases. These proteins have a core kinase domain flanked by unique amino- and carboxy-terminal domains. CDK proteins are known to regulate the cell cycle. All three PCTAIRE isoforms are abundantly expressed and catalytically active in post-mitotic brain, suggesting that they may function in processes other than cell division (1). PCTAIRE 1 is a cytoplasmic phosphoprotein whose kinase activity peaks in G2 and S phase (2). While one study indicates that noncovalent interactions with a regulatory component (such as a cyclin) are necessary for catalytic activity of PCTAIRE 1, others show that the monomeric protein is fully active (3). The Cdk5/p25 complex phosphorylates PCTAIRE 1 at Ser95, enhancing its kinase activity (4).
