General annotation (Comments)
| Function | 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. Ref.11 Ref.15 Ref.16 |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. |
| Subunit structure | Interacts with GABARAP and GABARAPL2. Interacts (via C-terminus) with ATG13. Part of a complex consisting of ATG13, ATG101, ULK1 and RB1CC1. 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. Interacts with FEZ1; SCOC interferes with FEZ1-binding. Interacts with TBC1D14. Ref.5 Ref.8 Ref.9 Ref.10 Ref.11 Ref.16 Ref.19 Ref.20 |
| Subcellular location | Cytoplasm › cytosol By similarity. Preautophagosomal structure By similarity. Note: Under starvation conditions, is localized to puncate structures primarily representing the isolation membrane that sequesters a portion of the cytoplasm resulting in the formation of an autophagosome By similarity. |
| Tissue specificity | Ubiquitously expressed. Detected in the following adult tissues: skeletal muscle, heart, pancreas, brain, placenta, liver, kidney, and lung. |
| Post-translational modification | Autophosphorylated. Phosphorylated under nutrient-rich conditions; dephosphorylated during starvation or following treatment with rapamycin. Under nutrient sufficiency, phosphorylated by MTOR/mTOR, disrupting the interaction with AMPK and preventing activation of ULK1 By similarity. In response to nutrient limitation, phosphorylated and activated by AMPK, leading to activate autophagy. Ref.18 |
| Sequence similarities | Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. APG1/unc-51/ULK1 subfamily. Contains 1 protein kinase domain. |
| Sequence caution | The sequence BAA34442.2 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened. |
