Mechanistically, LKB1-mediated phosphorylation increases intramolecular interactions in Sirt1, such as the binding of the C terminus to the deacetylase core domain, thereby eliminating DBC1 (Deleted in Breast Cancer 1, Sirt1 endogenous inhibitor) inhibition and promoting Sirt1-substrate interaction. |

It was shown that thr336 and thr366 are the major autophosphorylation sites of mouse lkb1 (sapkota et al., 2002). We confirmed these data on the human orthologues thr336 and thr363. Moreover, the enhanced stoichiometry of lkb1 autophosphorylation by strad enabled us to identify two novel sites: thr185 and thr402. We show that increased lkb1 autophosphorylation of all sites correlates with the activation of its catalytic activity. |

Lkb1 is a master kinase that activates 13 kinases of the ampk subfamily, including mark/par-1we recently demonstrated that the lkb1 tumour suppressor kinase, in complex with the pseudokinase strad and the scaffolding protein mo25, phosphorylates and activates amp-activated protein kinase (ampk). A total of 12 human kinases (nuak1, nuak2, brsk1, brsk2, qik, qsk, sik, mark1, mark2, mark3, mark4 and melk) are related to ampk. Here we demonstrate that lkb1 can phosphorylate the t-loop of all the members of this subfamily, apart from melk, increasing their activity >50-fold |

MARK family kinases can be activated by phosphorylation of a conserved threonine (Thr-208 in MARK2), and inactivated by phosphorylation of a serine (Ser-212), both in the activation loop of the catalytic domain. Activation is achieved by the kinases MARKK/TAO1 or LKB1, although the inactivating kinase was unknown. We show here that GSK3beta serves the role of the inhibitory kinase. |

In this study, we identified lkb1 as a new binding partner of appl1 and showed that the bar domain of appl1 is involved in this interaction.Here we show that in muscle cells adiponectin and metformin induce ampk activation by promoting appl1-dependent lkb1 cytosolic translocation. Appl1 mediates adiponectin signaling by directly interacting with adiponectin receptors and enhances lkb1 cytosolic localization by anchoring this kinase in the cytosol. |
