| Gene Variant Descriptions | MAP2K1 K57E lies within the negative regulatory region of the Map2k1 protein (PMID: 24241536). K57E confers a gain of function to Map2k1 as demonstrated by increased activation of downstream Erk1/2 (PMID: 24463458, PMID: 25370473) and increased transformation in cultured cells and increased proliferation in a competition assay (PMID: 36442478), and is associated with Braf inhibitor resistance in cell culture (PMID: 24463458, PMID: 25370473, PMID: 36442478). |
