Product Specific Information

This antibody was cross-adsorbed to a phospho-tyrosine peptide before affinity purification using phospho-p38alpha (Tyr-323) peptide (without carrier). The antibody detects a 38 kDa* band corresponding to p38alpha on SDS-PAGE immunoblots of human Jurkat, K562, and mouse macrophage (J774A.1) cells treated with pervanadate. In addition, the antibody detects recombinant p38 MAP Kinase when treated with Fyn kinase (The in vitro kinase model was kindly provided by Dr. Paul Mittelstadt from the Laboratory of Immune Cell Biology at the NCI.)

Target Information

MAPK14 (p38 alpha) is a member of the stress-activated protein kinase class of MAPKs. The p38 MAPK cascade regulates a variety of cellular responses to stress, inflammation, and other signals. p38 MAPK is relatively inactive in the nonphosphorylated form and becomes rapidly activated by dual phosphorylation of a Thr-Gly-Tyr motifs. There are four isoforms of p38 MAPK, which differ in their tissue expression and affinity for upstream activators and downstream effectors. When cells are exposed to tumor necrosis factor, interleukin-1, heat shock, or other activating stimuli, activation of MAPK kinase-3 occurs by phosphorylation. Activated MAPK kinase-3/6 phosphorylate each residue of Thr180 and Tyr182 in p38 MAPK. Phospho-p38 MAPK activates ATF-2, CHOP-1, MEF-2 and other transcription factors through phosphorylation.
