MAPK13

A gene on chromosome 6p21.31 that encodes a member of the MAP kinase family, which integrate multiple biochemical signals and are involved in cell proliferation, differentiation, transcription, regulation and development. MAPK13 is phosphorylated and activated by MAP kinases—especially MKK3 and MKK6; it is closely related to p38 MAP kinase and both are activated by pro-inflammatory cytokines and environmental stress, and in turn phosphorylate downstream targets.

The p38 MAPK family members (p38, MAPK11, SAPK3, and SAPK4) are activated by inflammatory cytokines, UV radiation, and external stress such as heat shock and high osmotic stress.
In rice, SAPK4 overexpression under salt stress significantly improved the seed germination, plant growth, and development.

To date, 4 isoforms of the p38 family have been identified: p38[alpha], p38[beta], p38[gamma] (extracellular signal-regulated kinases 6, SAPK3), and p38[delta] (SAPK4).
