Biochem/physiol Actions

As a member of the MAP kinase family, JNK1 is known to play a role in the induction of apoptosis through various stimuli such as TNFa.JNK1 also is influences cell migration via phosphorylation of paxillin.JNK1 is also a crucial mediator of obesity and insulin resistance and a potential target for therapeutics.

JNK1 (c-Jun N-terminal kinase 1) is a member of the MAPK (mitogen activated protein kinase) family that controls gene expression by phosphorylation of transcription factors. It is linked with apoptosis, brain development and learning ability. JNK1 also influences cell migration via phosphorylation of paxillin. JNK1 also regulates obesity and insulin resistance.
