Protocols
- 3042:
- Flow, Immunoprecipitation, Western Blotting
Specificity / Sensitivity
MAPKAPK-2 Antibody detects endogenous levels of total MAPKAPK-2 protein. This antibody does not cross-react with MAPKAPK-3 or -5.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to the carboxy-terminal region of human MAPKAPK-2. Antibodies are purified by protein A and peptide affinity chromatography.
Background
In response to cytokines, stress and chemotactic factors, MAP kinase-activated protein kinase 2 (MAPKAPK-2) is rapidly phosphorylated and activated. It has been shown that MAPKAPK-2 is a direct target of p38 MAPK (1). Multiple residues of MAPKAPK-2 are phosphorylated in vivo in response to stress. However, only four residues (Thr25, Thr222, Ser272 and Thr334) are phosphorylated by p38 MAPK in an in vitro kinase assay (2). Phosphorylation at Thr222, Ser272 and Thr334 appears to be essential for the activity of MAPKAPK-2 (2). Thr25 is phosphorylated by p42 MAPK in vitro, but is not required for the activation of MAPKAPK-2 (2).
