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 motif.
There are four isoforms of p38 MAPK, differing in 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.
