Gene PIK3CA
Variant K111N
Impact List missense
Protein Effect gain of function
Gene Variant Descriptions PIK3CA K111N lies within the region linking the PI3K-ABD and PI3K-RBD domains of the Pik3ca protein (UniProt.org). K111N results in increased phosphorylation of Akt, activation of downstream signaling, and is transforming in cell culture (PMID: 17376864, PMID: 29533785).

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.
