MAP2K1 | NCBI | CFC3|MAPKK1|MEK1|MEL|MKK1|PRKMK1 | MAP2K1 (MEK1), mitogen-activated protein kinase kinase 1, is a serine-threonine kinase, which activates the RAS-RAF-MEK-ERK pathway in cell proliferation and differentiation (PMID: 22753777). MAP2K1 (MEK1) activating mutations have been identified in a number of solid tumor types including, melanoma (PMID: 29753091), colorectal (PMID: 28819429), lung adenocarcinoma (PMID: 25351745, PMID: 32361034), histiocytic sarcoma (PMID: 29768143), and Map2k1 mutations are often associated with resistance to Mek and Raf inhibition (PMID: 29753091). | Oncogene |
