Gene Variant Descriptions | MAP2K1 F53L lies within the negative regulatory region of the Map2k1 protein (PMID: 24241536). F53L results in activation of Map2k1 as indicated by increased Erk and Mek phosphorylation (PMID: 25164765, PMID: 29483135), increased Rsk phosphorylation (PMID: 25351745), transformation activity in culture (PMID: 25351745, PMID: 36442478), and increased proliferation in a competition assay (PMID: 36442478), and demonstrates resistance to some Mek and Braf inhibitors (PMID: 29753091, PMID: 36442478). |
