STK11 - serine/threonine kinase 11 Gene
Also Known as PJS; LKB1; hLKB1
Species: Homo sapiens
About STK11
This gene has 9 transcripts (splice variants), 220 orthologues, 22 paralogues and is associated with 119 phenotypes. Broad expression in testis (RPKM 28.3), spleen (RPKM 10.4) and 25 other tissues.
Summary
The protein encoded by this gene is a serine/threonine kinase that regulates cell polarity and energy metabolism and functions as a tumor suppressor. Mutations in this gene have been associated with the autosomal dominant Peutz-Jeghers syndrome, as well as with skin, pancreatic, and testicular cancers. [provided by RefSeq, May 2022]
