Mitogen-activated protein kinase 14A
Serine/threonine kinase which acts as an essential component of the MAP kinase signal transduction pathway. Mapk14a is one 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. Required for cytokinesis on the future dorsal side of the blastodisc, suggesting a role in symmetrical and synchronous blastomere cleavage.
Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily.
