Protein Effect | gain of function |
Gene Variant Descriptions | MAP2K1 C121S lies within the protein kinase domain of the Map2k1 protein (UniProt.org). C121S confers a gain of function on the Map2k1 protein as demonstrated by increased Erk1/2 (PMID: 25899310) and Mek phosphorylation in culture and confers acquired resistance to Raf and Mek inhibitors (PMID: 21383288, PMID: 24448821, PMID: 29483135, PMID: 29753091). |
