Gene Symbol CBL
Synonyms C-CBL | CBL2 | FRA11B | NSLL | RNF55
Gene Description CBL, Cbl proto-oncogene, is an E3 ubiquitin-protein ligase involved in cell signaling and ubiquitination of tyrosine kinases (PMID: 23085373). CBL mutations, often resulting in a loss of function, have been identified primarily in myeloid neoplasms, including myelodysplastic syndrome, acute myeloid leukemia, chronic myeloid leukemia, myelofibrosis, and juvenile myelomonocytic leukemia (PMID: 25477533).

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.
