General description

Product Source: Expressed in E.coli
Recombinant human MAPKAP Kinase 2 (MAPKAP-K2), residues 46-400, A399G, containing an N-terminal GST tag

MAPKAP Kinase 2 has been implicted as a cell cycle checkpoint kinase, joining the ranks of Chk1 and Chk2 as critical regulators of the DNA damage response in mammalian cells in recent studies (Manke, et al, 2005, and Abraham, 2005). This research indicates that MAPKAP Kinase 2, a serine/threonine kinase activated by p38, phosphorylates CDC25 B/C, generating a binding site for 14-3-3 proteins. The checkpoint kinases Chk1 and Chk2 are targets for drug discovery efforts designed to overcome cell cycle arrest due to DNA damage induced by chemotherapeutic agents. Overriding the checkpoint kinases in cancer cells exposed to DNA damaging agents leads to catastrophic failure of cell division and apoptosis.
The new role of MAPKAP Kinase 2 in complementing the function of Chk1 and Chk2 suggests a new target for drug discovery efforts.

We have previously reported that in thrombin-stimulated human platelets, cytosolic phospholipase A(2) (cPLA2) is phosphorylated on Ser-505 by p38 protein kinase and on Ser-727 by an unknown kinase. Pharmacological inhibition of p38 leads to inhibition of cPLA2 phosphorylation at both

The success of anti-TNF biologics for the treatment of rheumatoid arthritis has highlighted the importance of understanding the intracellular pathways that regulate TNF production in the quest for an orally-available small molecule inhibitor. p38 is known to strongly regulate TNF

Dysfunctions in post-transcriptional control are observed in cancer and chronic inflammatory diseases. Here, we employed a kinome inhibitor library (n = 378) in a reporter system selective for 3'-untranslated region-AU-rich elements (ARE). Fifteen inhibitors reduced the ARE-reporter activity; among the targets is

A novel protein kinase, which was only active when phosphorylated by the mitogen-activated protein kinase (MAP kinase), has been purified 85,000-fold to homogeneity from rabbit skeletal muscle. This MAP kinase activated protein kinase, termed MAPKAP kinase-2, was distinguished from S6

The substrate specificity of mitogen-activated protein (MAP) kinase-activated protein kinase-2 (MAPKAP kinase-2) was investigated by using synthetic peptides related to the N-terminus of glycogen synthase. The minimum sequence required for efficient phosphorylation was found to be Xaa-Xaa-Hyd-Xaa-Arg-Xaa-Xaa-Ser-Xaa-Xaa, where Hyd is
