Variant | I103_K104del |
Impact List | deletion |
Protein Effect | gain of function |
Gene Variant Descriptions | MAP2K1 I103_K104del results in the deletion of two amino acids in the Map2k1 protein from amino acids 103 to 104 (UniProt.org). I103_K104del 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 Mek and Erk phosphorylation in culture (PMID: 28935960, PMID: 30377225), increased proliferation in a competition assay, and increased transformation activity in culture (PMID: 36442478). |
