Gene | MAP2K1 |
Variant | G61_D65del |
Impact List | deletion |
Protein Effect | gain of function |
Gene Variant Descriptions | MAP2K1 G61_D65del results in the deletion of five amino acids in the Map2k1 protein from amino acids 61 to 65 (UniProt.org). G61_D65del confers a gain of function to Map2k1 as demonstrated by increased proliferation in a competition assay and increased transformation activity in cultured cells (PMID: 36442478). |
