NCIt definition : Human STK11 wild-type allele is located in the vicinity of 19p13.3 and is approximately
23 kb in length. This allele, which encodes serine/threonine-protein kinase STK11
protein, is involved in cell cycle arrest at the G1 checkpoint and regulation of cell
polarity. Certain allelic variants of the STK11 gene cause Peutz-Jeghers syndrome,
a hereditary disease characterized by predisposition to benign and malignant tumors
of many organ systems.;
NCIt note : The STK11 gene is a tumor suppressor gene. Decreased expression of this gene in breast
carcinomas is associated with shorter relapse-free survival. Studies in mice have
shown that the STK11 gene plays a critical role in glucose production by the liver.;
