Gene RB1
Variant R661W
Impact List missense
Protein Effect unknown
Gene Variant Descriptions RB1 R661W lies within the B domain of the Rb1 protein (UniProt.org). R661W results in growth suppression similar to wild-type Rb1 (PMID: 9342358, PMID: 15688068) but results in loss of transcriptional repression (PMID: 8524800), decreased induction of G0/G1 block and p27 expression, reduced downregulation of cyclin E in cultured cells (PMID: 17163992), decreased binding to large T antigen in a yeast two-hybrid assay (PMID: 9342358), and fails to bind E2f1 in in vitro assays (PMID: 9342358, PMID: 15688068), and therefore, its effect on Rb1 protein function is unknown.

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.
