Gene CHEK2
Variant R3W
Impact List missense
Protein Effect unknown
Gene Variant Descriptions CHEK2 R3W does not lie within any known functional domains of the Chek2 protein (UniProt.org). The functional effect of R3W is conflicting, as it results in cell proliferation similar to wild-type Chek2 in a yeast assay in one study (PMID: 30851065), however, results in intermediate cell proliferation relative to wild-type Chek2 in another study (PMID: 22419737), and similar Kap1 phosphorylation at serine (S)-473 in cell culture and in vitro assays (PMID: 31050813), and therefore, its effect on Chek2 protein function is unknown.

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.
