Impact List | deletion |
Protein Effect | gain of function |
Gene Variant Descriptions | MAP2K1 E102_I103del results in the deletion of two amino acids in the protein kinase domain of the Map2k1 protein from amino acids 102 to 103 (UniProt.org). E102_I103del confers a gain of function to the Map2k1 protein as demonstrated by activity independent of Raf and increased phosphorylation of Mek and Erk relative to wild-type Map2k1 (PMID: 29483135), increased Erk phosphorylation (PMID: 32036070, PMID: 25202140) and Mek homodimerization in culture (PMID: 30377225), increased proliferation in a competition assay, and increased transformation activity in culture (PMID: 36442478). |
