Biological Activity
Mitogen-activated protein kinases (MAPKs) are serine/threonine kinases which play a central role in mitogenic signaling. The MAPKs function to transduce extracellular signals to intracellular targets, including transcription factors controlling the expression of genes essential to many cellular processes including proliferation, development and differentiation. JNK1 is essential for tumor necrosis factor alpha (TNF-α)-induced c-Jun kinase activation, c-Jun expression, and apoptosis. JNK1 and JNK2 participates in the survival of neuronal cells.
