Background Information

Mitogen-activated protein kinase kinase 4 (MAP2K4), also known as MAP kinase kinase 4 (MKK4), is a second-level kinase in the hierarchical mitogen-activated protein kinase (MAPK) pathway and is regulated by Ras. MAP2K4 has been found to be stably mutated in 3-5 % of cancers, such as ovarian, prostate, and liver cancers. MAP2K4 is activated by MEKK1 or ASK1/TAK1/MLK3. It is unique among all known MAP2Ks in its ability to phosphorylate two different MAPKs, p38 and JNK (c-Jun N-terminal kinase), respectively. (PMID: 24487067, PMID: 33341545)
