Constitutive activity of JNK2 alpha2 is dependent on a unique mechanism of MAPK activation.

Abstract excerpt

c-Jun N-terminal kinases (JNKs) are part of the mitogen-activated protein kinase (MAPK) family and are important regulators of cell growth, proliferation, and apoptosis. Typically, a sequential series of events are necessary for MAPK activation: phosphorylation, dimerization, and then subsequent translocation to the nucleus. Interestingly, a constitutively active JNK isoform, JNK2alpha2, possesses the ability to...
