Background Information
Liver kinase 1 (LKB1 also known as STK11) is a tumor suppressor gene that is inactivated by bi-allelic mutation in non-small cell lung cancer (NSCLC), malignant melanoma and cervical cancer. LKB1 protein has a central kinase domain, two N-terminal nuclear leading sequences, and a C-terminal regulatory motif. The protein also contains a CAAX motif at C-terminal end and can be farnesylated. The formation of an LKB1/Strad/MO25 complex is essential for LKB1's kinase activity, and there are at least 13 known substrates of LKB1, which includes AMPKs, BRSKs, and MARKs. LKB1 is the major kinase that phosphorylates the AMPK activation loop in conditions of energy stress. (PMID: 25679014, PMID: 19629071)
