Catalytic domain of the Serine/Threonine Kinase, c-Jun N-terminal Kinase 2. Serine/Threonine Kinases (STKs), c-Jun N-terminal kinase 2 (JNK2) subfamily, catalytic (c) domain. STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The JNK2 subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase. JNKs are mitogen-activated protein kinases (MAPKs) that are involved in many stress-activated responses including those during inflammation, neurodegeneration, apoptosis, and persistent pain sensitization, among others. Vetebrates harbor three different JNK genes (Jnk1, Jnk2, and Jnk3). JNK1, like JNK2, is expressed in every cell and tissue type. Initially it was thought that JNK1 and JNK2 were functionally redundant as mice deficient in either genes (Jnk1 or Jnk2) could survive but disruption of both genes resulted in lethality. However, recent studies have shown that JNK1 and JNK2 perform distinct functions through specific binding partners and substrates. JNK2 is specifically translocated to the mitochondria during dopaminergic cell death. Specific substrates include the microtubule-associated proteins DCX and Tau, as well as TIF-IA which is involved in ribosomal RNA synthesis regulation. Mice deficient in Jnk2 show protection against arthritis, type 1 diabetes, atherosclerosis, abdominal aortic aneurysm, cardiac cell death, TNF-induced liver damage, and tumor growth, indicating that JNK2 may play roles in the pathogenesis of these diseases.

Tips:  If you've navigated here from a protein, hovering over a position on the weblogo will display the corresponding protein position for that domain position. The histograms below the weblogo indicate mutations found on the domain. Red is for disease (OMIM) and blue is for SNPs. Functional Features are displayed as orange boxes under the histograms. You can choose which features are displayed in the box below. Range on the Protein: Protein ID Protein Position Domain Position:
