Mitogen-activated protein kinase 14 (MAPK14)

Serine/threonine kinase which functions as an essential component of the MAP kinase signal transduction pathway. MAPK14 is one of the four p38 MAPKs which play an significant role in the cascades of cellular responses evoked by extracellular stimuli such as proinflammatory cytokines or physical strain leading to direct activation of transcription factors.

Accordingly, p38 MAPKs phosphorylate a wide assortment of proteins and it has been estimated that they might have approximately 200 to 300 substrates each. A few of the targets are downstream kinases that are activated through phosphorylation and additional phosphorylate additional targets.
