MAP3K5 (ASK1) is a serine/threonine kinase that is abundantly expressed in human heart and pancreas and are activated in response to various extracellular stimuli, including cytokines, growth factors and environmental stresses. A novel MAP kinase kinase kinase (MAPKKK) was identified and designated ASK1 (for apoptosis signal-regulating kinase 1) and MAPKKK5. ASK1 activates two different subgroups of MAPKK, MKK4 and MKK6, which in turn activates c-Jun N-terminal kinase (JNK) and p38 MAP kinase, respectively. ASK1/MAPKKK5 is activated by TNFR and Fas through the interaction with members of the TRAF family and Fas-associated protein Daxx. Overexpression of ASK1 induced apoptotic cell death and a catalytically inactive form of ASK1 inhibited TNF-a-induced apoptosis. ASK1 is expressed in variety of human and mouse tissues.
