Gene Symbol U2AF1
Synonyms FP793 | RN | RNU2AF1 | U2AF35 | U2AFBP
Gene Description U2AF1, U2 small nuclear RNA auxiliary factor 1, is a 35 kDa subunit splicing factor, that functions in 3' splice site recognition to regulate expression of genes involved in hematological and solid tumor development (PMID: 2963698, PMID: 28986033, PMID: 32303702). U2AF1 is frequently mutated in myelodysplatic syndrome (MDS), chronic myelomonocytic leukemia, atypical CML, acute myeloid leukemia, and lung adenocarcinoma (PMID: 23645565, PMID: 22678168, PMID: 24498085, PMID: 30138727, PMID: 29991672).

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.
