[[http://www.uniprot.org/uniprot/STK11_HUMAN STK11_HUMAN]] Defects in STK11 are a cause of Peutz-Jeghers syndrome (PJS) [MIM:[http://omim.org/entry/175200 175200]]. PJS is a rare hereditary disease in which there is predisposition to benign and malignant tumors of many organ systems. PJS is an autosomal dominant disorder characterized by melanocytic macules of the lips, multiple gastrointestinal hamartomatous polyps and an increased risk for various neoplasms, including gastrointestinal cancer.<ref>PMID:9425897</ref> <ref>PMID:9760200</ref> <ref>PMID:9428765</ref> <ref>PMID:10408777</ref> <ref>PMID:12372054</ref> <ref>PMID:21411391</ref> Defects in STK11 have been associated with testicular germ cell tumor (TGCT) [MIM:[http://omim.org/entry/273300 273300]]. A common solid malignancy in males. Germ cell tumors of the testis constitute 95% of all testicular neoplasms.<ref>PMID:9605748</ref> <ref>PMID:9887330</ref> Note=Defects in STK11 are associated with some sporadic cancers, especially lung cancers. Frequently mutated and inactivated in non-small cell lung cancer (NSCLC). Defects promote lung cancerigenesis process, especially lung cancer progression and metastasis. Confers lung adenocarcinoma the ability to trans-differentiate into squamous cell carcinoma. Also able to promotes lung cancer metastasis, via both cancer-cell autonomous and non-cancer-cell autonomous mechanisms.

[[http://www.uniprot.org/uniprot/1433Z_HUMAN 1433Z_HUMAN]] Adapter protein implicated in the regulation of a large spectrum of both general and specialized signaling pathways. Binds to a large number of partners, usually by recognition of a phosphoserine or phosphothreonine motif. Binding generally results in the modulation of the activity of the binding partner.<ref>PMID:9360956</ref> <ref>PMID:14578935</ref> <ref>PMID:15071501</ref> <ref>PMID:15644438</ref> <ref>PMID:16376338</ref> [[http://www.uniprot.org/uniprot/STK11_HUMAN STK11_HUMAN]] Tumor suppressor serine/threonine-protein kinase that controls the activity of AMP-activated protein kinase (AMPK) family members, thereby playing a role in various processes such as cell metabolism, cell polarity, apoptosis and DNA damage response. Acts by phosphorylating the T-loop of AMPK family proteins, leading to promote their activity: phosphorylates PRKAA1, PRKAA2, BRSK1, BRSK2, MARK1, MARK2, MARK3, MARK4, NUAK1, NUAK2, SIK1, SIK2, SIK3 and SNRK but not MELK. Also phosphorylates non-AMPK family proteins such as STRADA and possibly p53/TP53. Acts as a key upstream regulator of AMPK by mediating phosphorylation and activation of AMPK catalytic subunits PRKAA1 and PRKAA2: it thereby regulates inhibition of signaling pathways that promote cell growth and proliferation when energy levels are low, glucose homeostasis in liver, activation of autophagy when cells undergo nutrient deprivation, B-cell differentiation in the germinal center in response to DNA damage. Also acts as a regulator of cellular polarity by remodeling the actin cytoskeleton. Required for cortical neurons polarization by mediating phosphorylation and activation of BRSK1 and BRSK2, leading to axon initiation and specification. Involved in DNA damage response: interacts with p53/TP53 and recruited to the CDKN1A/WAF1 promoter to participate in transcription activation. Able to phosphorylate p53/TP53; the relevance of such result in vivo is however unclear and phosphorylation may be indirect and mediated by downstream STK11/LKB1 kinase NUAK1 Also acts as a mediator p53/TP53-dependent apoptosis via interaction with p53/TP53: translocates to mitochondrion during apoptosis and regulates p53/TP53-dependent apoptosis pathways.<ref>PMID:11430832</ref> <ref>PMID:12805220</ref> <ref>PMID:14517248</ref> <ref>PMID:15016379</ref> <ref>PMID:14976552</ref> <ref>PMID:15733851</ref> <ref>PMID:17108107</ref> <ref>PMID:21317932</ref>
