Gene MAP2K1
Variant L42F
Impact List missense
Protein Effect gain of function - predicted
Gene Variant Descriptions MAP2K1 L42F lies within the negative regulatory region of the Map2k1 protein (PMID: 24241536). L42F results in autophosphorylation and kinase activity similar to wild-type Map2k1 in in vitro assays (PMID: 29753091), proliferation similar to wild-type in a competition assay, but increased transformation activity (PMID: 36442478) and increased Erk phosphorylation in cultured cells (PMID: 32641410), and therefore, is predicted to lead to a gain of Map2k1 protein function.

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.
