      Background InformationThe p38 family refers to the SAPK2/3 Kinases (Stess-Activated Protein Kinases), a subfamily of JNK/SAPK family. p38/SAPK Kinases are also activated by stresses, most notably inflammatory cytokines, irradiation, and certain toxins such as anisomycin and arsenite. SAPKs have been implicated in many pathological conditions, including inflammation, cancer and neurodegenerative diseases. As with the other MAPK family members (ERK, JNK, p38MAPK, and ERK5), p38 is activated through phosphorylation on both threonine and tyrosine residues at the Thr-X-Tyr dual phosphorylation motif, where X is Gly for p38. Once phosphorylated and active, it then goes on to phosphorylate downstream targets in both the cytoplasm and the nucleus. Some of their main targets of p38 are the kinase MAPKAPK2 and the transcription factor ATF2 that are activated via their phosphorylation.

      UniProt Number
      UniProt SummaryFUNCTION: 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.
