MAPK9-V1 JNK2A1
12 splicing 4336 - 424 - 2011 21357683
  • MAPK9-V2 JNK2A2
  • differs from other MAPK proteins in two major ways; its autoactivation/autophosphorylation is dependent on dimerization, and dimerization most likely precedes autophosphorylation

    basic FUNCTION
  • playing a role in the signal transduction pathway initiated by proinflammatory cytokines and UV radiation
  • playing a necessary role for epithelial morphogenesis and essential regulator of signal transduction by the EGF receptor in the epidermis
  • MAP3K1-MAPK8/9 axis governs the JNK activation levels to control downstream transcriptional events and eyelid morphogenesis and reduction of upstream MAP3K1 signals uncovers analogous but differential roles of MAPK8 and MAPK9 in a biological process
  • both MAPK8 and MAPK9, have cytotoxic potential, however MAPK9 is the primary signal transducer
  • prevents Ras-induced cell senescence and growth arrest by reducing the expression levels of the cell cycle inhibitor CDKN1B and the activation of NF-kappaB
  • role of JNK2 in the mechanism of osmotic stress-induced tight junction disruption in the intestinal epithelium
  • critically involved in stress-induced deficit of contextual fear
  • plays a key role in Ras-induced tumorigenesis
  • critical role for MAPK9 and EPS8 in receptor tyrosine kinase signaling and trafficking to convey distinctly different effects on cell migration
  • enhances growth factor-induced cell migration by regulating RTK trafficking and modulating EPS8 levels
  • MAPK10 mediates potentially its effects mainly at the transcriptional level, while MAPK8 or MAPK9 appear to mediate their pro-apoptotic effect in the cytoplasm
  • CELLULAR PROCESS cell life, proliferation/growth
