DESCRIPTION

Also known as ULK1_HUMAN, ULK1, KIAA0722. Serine/threonine-protein kinase involved in autophagy in response to starvation (PubMed:18936157, PubMed:21460634, PubMed:21795849, PubMed:23524951, PubMed:25040165, PubMed:31123703). Acts upstream of phosphatidylinositol 3-kinase PIK3C3 to regulate the formation of autophagophores, the precursors of autophagosomes (PubMed:18936157, PubMed:21460634, PubMed:21795849, PubMed:25040165). 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 (PubMed:21795849). 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 (PubMed:21460634). May phosphorylate ATG13/KIAA0652 and RPTOR; however such data need additional evidences (PubMed:18936157). Plays a role early in neuronal differentiation and is required for granule cell axon formation (PubMed:11146101). May also phosphorylate SESN2 and SQSTM1 to regulate autophagy (PubMed:25040165). Phosphorylates FLCN, promoting autophagy (PubMed:25126726). Phosphorylates AMBRA1 in response to autophagy induction, releasing AMBRA1 from the cytoskeletal docking site to induce autophagosome nucleation (PubMed:20921139). Interacts with GABARAP and GABARAPL2 (PubMed:11146101). Interacts (via C-terminus) with ATG13 (PubMed:18936157). Part of a complex consisting of ATG13, ATG101, ULK1 and RB1CC1 (PubMed:19287211). Associates with the mammalian target of rapamycin complex 1 (mTORC1) through an interaction with RPTOR; the association depends on nutrient conditions and is reduced during starvation (PubMed:19211835, PubMed:21795849). Interacts with FEZ1; SCOC interferes with FEZ1-binding (PubMed:22354037). Interacts with TBC1D14 (PubMed:22613832). Interacts (phosphorylated form) with TRIM5 (PubMed:25127057). When phosphorylated at Ser-317, interacts with MEFV and BECN1 simultaneously (PubMed:26347139). Interacts with TRIM21 and IRF3, in the presence of TRIM21 (PubMed:26347139). Interacts with SESN2 (PubMed:25040165). Interacts with SQSTM1 (PubMed:25040165). Interacts with C9orf72 (PubMed:27334615). Interacts with WDR45 (PubMed:28561066). Interacts with ATG13; this interaction is increased in the absence of TMEM39A (PubMed:31806350). Interacts with WIPI2 (PubMed:28890335). Interacts with ATP2A2 (PubMed:28890335). Interacts with AMBRA1 (PubMed:25438055, PubMed:31123703).
