Gene Symbol STK11
Synonyms hLKB1 | LKB1 | PJS
Gene Description STK11, serine/threonine kinase 11, is a tumor suppressor (PMID: 30562755) involved in cell metabolism, growth, polarity, and tumor suppression through the regulation of AMPK family members (PMID: 26398719). STK11 germline mutations are common in Peutz-Jeghers syndrome and somatic STK11 mutations have been identified in melanoma, lung, pancreatic, cervical, and endometrial cancers (PMID: 26877140, PMID: 29191602) and are often associated with resistance to immune checkpoint blockcade (PMID: 30626603).

  • 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"


  • 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.

Variant Impact Protein Effect Variant Description Associated with drug Resistance
inact mut unknown loss of function STK11 inact mut indicates that this variant results in a loss of function of the Stk11 protein. However, the specific amino acid change has not been identified.
mutant unknown unknown STK11 mutant indicates an unspecified mutation in the STK11 gene.
