Abstract Text

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.

MAP2K1 NCBI CFC3|MAPKK1|MEK1|MEL|MKK1|PRKMK1 MAP2K1 (MEK1), mitogen-activated protein kinase kinase 1, is a serine-threonine kinase, which activates that RAS-RAF-MEK-ERK pathway in cell proliferation and differentiation (PMID: 22753777). MAP2K1 (MEK1) activating mutations have been identified in a number of solid tumor types including, melanoma (PMID: 29753091), colorectal (PMID: 28819429), lung adenocarcinoma (PMID: 25351745, PMID: 32361034), histiocytic sarcoma (PMID: 29768143), and Map2k1 mutations are often associated with resistance to Mek and Raf inhibition (PMID: 29753091).
