Catalytic domain of the Serine/Threonine Kinase, c-Jun N-terminal Kinase 3. Serine/Threonine Kinases (STKs), c-Jun N-terminal kinase 3 (JNK3) subfamily, catalytic (c) domain. STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The JNK3 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). JNK3 is expressed primarily in the brain, and to a lesser extent in the heart and testis. Mice deficient in Jnk3 are protected against kainic acid-induced seizures, stroke, sciatic axotomy neural death, and neuronal death due to NGF deprivation, oxidative stress, or exposure to beta-amyloid peptide. This suggests that JNK3 may play roles in the pathogenesis of these diseases.
