Gene MAP2K1
Variant L177M
Impact List missense
Protein Effect gain of function
Gene Variant Descriptions MAP2K1 L177M lies within the protein kinase domain of the Map2k1 protein (UniProt.org). L177M confers a gain of function to the Map2k1 protein as indicated by a moderate increase in basal Erk signaling, sensitivity to Raf pathway activation (PMID: 29483135), and increased Erk phosphorylation in cultured cells (PMID: 32641410).

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.
