Gene CHEK2
Variant E239K
Impact List missense
Protein Effect loss of function
Gene Variant Descriptions CHEK2 E239K lies within the protein kinase domain of the Chek2 protein (UniProt.org). E239K results in Kap1 phosphorylation and Chek2 autophosphorylation similar to wild-type Chek2 in culture (PMID: 37449874) and Chek2 expression similar to wild-type in culture in one study (PMID: 31780696), but confers a loss of function to Chek2 as demonstrated by reduced Chek2-mediated DNA damage repair in yeast (PMID: 22419737), and decreased Chek2 protein expression and phosphorylation in cultured cells (PMID: 33606978), and decreased kinase activity in an in vitro assay (PMID: 31780696).

Filtering

  • Case insensitive filtering will display rows if any text in any cell matches the filter term
  • Use simple literal full or partial string matches
  • Separate multiple filter terms with a space. Any order may be used (i. e. a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page. Filtering has no impact on query parameters.
  • Use quotes to match on a longer phrase with spaces (i.e. "mtor c1483f")

Sorting

  • Generally, the default sort order for tables is set to be first column ascending; however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column. Be sure to set ascending or descending order for a given column before moving on to the next column.
