General description
Mitogen-Activated Protein Kinase Kinase 4 (MEK 4 or MKK4) is a 42 kDa member of a tyrosine/threonine protein kinase family that activates the c-Jun NH2-terminal kinases (JNK), which is part of the inflammation/stress signaling pathway. The mutation of the MEK 4 gene in some carcinomas indicates that it may also have a role as a tumor suppressor. Phosphorylation of MEK4 by MEKK1 on serine 257 and threonine 261 in the catalytic domain activates the protein and enables MEK 4 to phosphorylate JNK
This antibody specifically recognizes human MEK 4 double phosphorylated at serine 257 and threonine 261. Mouse and frog MEK 4 (100% homology) may cross react.

The Mitogen-Activated Protein Kinase Kinase 4 (MKK4), a member of the MAP kinase kinase family, directly phosphorylates and activates the c-Jun NH2-terminal kinases (JNK), in response to cellular stresses and proinflammatory cytokines. JNK is a member of the MAP kinase
R J Davis
Biochemical Society symposium, 64, 1-12 (1999-04-20)
The c-Jun N-terminal kinase (JNK) group of mitogen-activated protein kinases (MAP kinases) is activated by exposure of cells to environmental stress and by the treatment of cells with cytokines. The mechanism of activation of JNK is mediated by dual phosphorylation
C Hagemann et al.
Cellular signalling, 13(12), 863-875 (2001-12-01)
MEK kinases (MEKKs) comprise a family of related serine-threonine protein kinases that regulate mitogen-activated protein kinase (MAPK) signalling pathways leading to c-Jun NH2-terminal kinase (JNK) and p38 activation, induced by cellular stress (e.g., UV and gamma irradiation, osmotic stress, heat
