Gene Symbol ZRSR2
Synonyms U2AF1-RS2 | U2AF1L2 | U2AF1RS2 | URP | ZC3H22
Gene Description ZRSR2, zinc finger CCCH-type, RNA binding motif and serine/arginine rich 2, is a component of the splicesome that functions in 3' splice site recognition, therefore regulates expression of E2F transcription factors and genes in the Mapk/Erk pathways (PMID: 21041408, PMID: 25586593). ZRSR2 mutations are associated with myelodysplastic syndromes and acute myeloid leukemia, particularly in males (PMID: 21909114, PMID: 26769228).

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.
