Gene MLH1
Variant S44F
Impact List missense
Protein Effect loss of function
Gene Variant Descriptions MLH1 S44F lies within the ATPase domain of the Mlh1 protein (PMID: 22753075). S44F results in decreased mismatch repair (MMR) activity in in vitro assays (PMID: 17510385, PMID: 15475387) and in cell culture (PMID: 31784484), loss of interaction with Pms2 and Exo1 in yeast two-hybrid assays, and loss of repression activity in a yeast reporter assay (PMID: 12810663).

Filtering

  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (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 a longer phrase which contains spaces "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.
