p38 MAPK alpha (MAPK14), p38 MAPK beta (MAPK11), and p38 MAPK delta (MAPK13) are serine/threonine kinases which act as an essential component of the MAPkinase signal transduction pathway. p38 MAPK alpha, p38 MAPK beta, and p38 MAPK delta are three of the four p38 MAPKs which play an important role in the cascades of cellular responses evoked by extracellular stimuli such as proinflammatory cytokines or physical stress leading to direct activation of transcription factors. Accordingly, p38 MAPKs phosphorylate a broad range of proteins and it has been estimated that they may have approximately 200 to 300 substrates each. Some of the targets are downstream kinases which are activated through phosphorylation and further phosphorylate additional targets.
