Gene JAK3
Variant I87T
Impact List missense
Protein Effect gain of function
Gene Variant Descriptions JAK3 I87T lies within the FERM domain of the Jak3 protein (UniProt.org). I87T confers a gain of function to Jak3, as demonstrated by increased Jak3 autophosphorylation (PMID: 29046866), constitutive phosphorylation of downstream Stat5, and is transforming in cell culture (PMID: 18397343).

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.
