| Gene Variant Descriptions | CHEK2 A247D lies within the protein kinase domain of the Chek2 protein (UniProt.org). A247D confers a loss of function to Chek2 as demonstrated by decreased Chek2 protein expression and instability compared to wild-type Chek2 (PMID: 11719428), decreased Kap1 phosphorylation upon ionizing radiation in culture (PMID: 34903604), and decreased Kap1 phosphorylation and Chek2 autophosphorylation in culture (PMID: 37449874). |
