Structure of ULK1 bound to an inhibitor
Structural highlights
Function[ULK1_HUMAN] Serine/threonine-protein kinase involved in autophagy in response to starvation. Acts upstream of phosphatidylinositol 3-kinase PIK3C3 to regulate the formation of autophagophores, the precursors of autophagosomes. Part of regulatory feedback loops in autophagy: acts both as a downstream effector and negative regulator of mammalian target of rapamycin complex 1 (mTORC1) via interaction with RPTOR. Activated via phosphorylation by AMPK and also acts as a regulator of AMPK by mediating phosphorylation of AMPK subunits PRKAA1, PRKAB2 and PRKAG1, leading to negatively regulate AMPK activity. May phosphorylate ATG13/KIAA0652 and RPTOR; however such data need additional evidences. Plays a role early in neuronal differentiation and is required for granule cell axon formation.[1] [2] [3] Publication Abstract from PubMedAutophagy is a conserved cellular process that involves the degradation of cellular components for energy maintenance and cytoplasmic quality control that has recently gained interest as a novel target for a variety of human diseases, including cancer. A prime candidate to determine the potential therapeutic benefit of targeting autophagy is the kinase ULK1, whose activation initiates autophagy. Here, we report the first structures of ULK1, in complex with multiple potent inhibitors. These structures show features unique to the enzyme and will provide a path for the rational design of selective compounds as cellular probes and potential therapeutics.
