Gene VHL
Variant V155A
Impact List missense
Protein Effect loss of function - predicted
Gene Variant Descriptions VHL V155A lies within the CCT complex-binding region of the Vhl protein (UniProt.org). V155A retains the ability to bind the Elongin BC complex and ubiquitinate Hif1a in in vitro assays (PMID: 26503325), however, is predicted to lead to a loss of Vhl protein function as demonstrated by increased ubiquitination by Ube2s leading to reduced Vhl protein stability and impaired ability to adequately regulate Hif protein expression and activity in in vitro assays and cell culture (PMID: 26503325).

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.
