Application | Comment | Organism |
---|---|---|
medicine | acts as tumor suppressor, but can also promote tumor growth, plays a role in liver formation, the immune system and cardiac hypertrophy, contributes to optimal c-Jun N-terminal kinase activation | Mus musculus |
medicine | important role for MKK4 pathways in controlling cancer development, has a tumor suppression function, the MKK4 gene is mutated at a frequency of 5% in a number of cancer types. In contrast, studies in other cell types suggest that MKK4 and c-Jun N-terminal kinase participate in tumor promotion | Homo sapiens |
medicine | targets c-Jun N-terminal kinase but not p38 | Drosophila melanogaster |

additional information | overexpression of a constitutively active mutant of MKK4 in bronchial epithelial cell lines increases their proliferation and invasive properties | Homo sapiens |
additional information | targeted deletion of the Mkk4 gene, results in early embryonic lethality, anemia, severe hemorrhaging in the liver, impaired liver formation and abnormal hepatogenesis, which correlates with significant apoptosis of liver cells, and greatly reduced thymus size. In Mkk4-/- embryonic stem cells there is no defect in p38 activation in response to a number of stresses | Mus musculus |
