Gene MAP2K1
Variant K57_G61del
Impact List deletion
Protein Effect gain of function
Gene Variant Descriptions MAP2K1 K57_G61del results in the deletion of five amino acids of the Map2k1 protein from amino acids 57 to 61 (UniProt.org). K57_G61del results in proliferation in low serum conditions similar to wild-type Map2k1 (PMID: 36442478), but increased Erk phosphorylation in cultured cells (PMID: 32641410), increased proliferation in high serum conditions in a competition assay, and increased transformation in culture (PMID: 36442478).

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.
