Gene BRAF
Variant G466V
Impact List missense
Protein Effect loss of function
Gene Variant Descriptions BRAF G466V lies within the protein kinase domain of the Braf protein (UniProt.org). G466V results in impaired Braf kinase activity, but paradoxically activates MEK and ERK through transactivation of CRAF in cell culture (PMID: 22649091, PMID: 28783719), and in one of two cell lines, G466V decreased cell proliferation and cell viability as compared to wild-type Braf (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.
