Polyclonal Rabbit Affinity Purified E B IC FC
The stress-activated protein kinase/Jun terminal kinase SAPK/JNK is potently and preferentially activated by a variety of environmental stresses, including UV and gamma radiation, ceramides, inflammatory cytokines and, in some instances, by growth factors and GPCR agonists. As with the other MAPKs, the core signaling unit is composed of an MAPKKK, typically MEKK14, or a member of the mixed lineage kinases (MLKs) that would phosphorylate and activate MKK47, the SAPK/JNK kinase. Stress signals are delivered to this cascade by members of small GTPases of the Rho family (Rac, Rho, cdc42). Both Rac1 and cdc42 mediate the stimulation of MEKKs and MLKs. Alternatively, MKK47 can be activated in a pathway independent of small GTPases via stimulation of a member of the germinal center kinase (GCK) family. There are three SAPK/JNK genes with further diversification from alternative splicing. SAPK/JNK, when active as a dimer, can translocate to the nucleus where it regulates transcription through its effects on c-Jun, ATF-2 and other transcription factors.
