General description
FUNCTION: SwissProt: Q16539 # Responds to activation by environmental stress, pro- inflammatory cytokines and lipopolysaccharide (LPS) by phosphorylating a number of transcription factors, such as ELK1 and ATF2 and several downstream kinases, such as MAPKAPK2 and MAPKAPK5. Plays a critical role in the production of some cytokines, for example IL-6. May play a role in stabilization of EPO mRNA during hypoxic stress. Isoform Mxi2 activation is stimulated by mitogens and oxidative stress and only poorly phosphorylates ELK1 and ATF2. Isoform Exip may play a role in the early onset of apoptosis.
COFACTOR: Magnesium.
SIZE: 360 amino acids; 41293 Da
SUBUNIT: Binds to a kinase interaction motif within the protein tyrosine phosphatase, PTPRR. This interaction retains MAPK14 in the cytoplasm and prevents nuclear accumulation. Interacts with SPAG9 (By similarity). Interacts with NP60.
SUBCELLULAR LOCATION: Cytoplasm (By similarity). Nucleus (By similarity).
TISSUE SPECIFICITY: Brain, heart, placenta, pancreas and skeletal muscle. Expressed to a lesser extent in lung, liver and kidney.DOMAIN:SwissProt: Q16539 The TXY motif contains the threonine and tyrosine residues whose phosphorylation activates the MAP kinases.
PTM: Dually phosphorylated on Thr-180 and Tyr-182, which activates the enzyme. & Phosphorylated upon DNA damage, probably by ATM or ATR.
SIMILARITY: Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily. & Contains 1 protein kinase domain.
