Supplementary information

ULK1 also known as Unc-51-like kinase 1 is a serine/threonine-protein kinase with a molecular mass of approximately 112 kDa. ULK1 is expressed in many tissues including the brain heart and skeletal muscle and plays a significant mechanical role in initializing autophagy—a process vital for cellular recycling and homeostasis. The protein interacts with several autophagy-related proteins to facilitate its functions.
Biological function summary

This protein serves as an essential part of the ULK1 complex which includes ATG13 FIP200 and ATG101. This complex acts as an important regulator in the initiation stage of autophagy responding to cellular nutrient status and energy levels. ULK1 activity promotes the formation of the phagophore which is important for capturing and degrading cytoplasmic content.

Pathways

ULK1 plays a major role in autophagy and mTOR signaling pathways. The mTOR complex 1 (mTORC1) inhibits ULK1 activity under nutrient-rich conditions preventing unnecessary autophagy. When nutrients are scarce mTORC1 inhibition releases ULK1 enhancing autophagy initiation. ULK1 also interacts with AMPK an energy-sensing kinase adjusting cellular processes according to energy levels and promoting autophagy when necessary.

Research links ULK1 to cancer and neurodegenerative diseases. Deregulation of autophagy pathways influenced by impaired ULK1 activity associates with cancer progression and tumor growth. Cancer cells often exploit autophagy to survive in nutrient-poor environments. In neurodegenerative diseases such as Alzheimer's ULK1-mediated autophagy activity can help clear protein aggregates. Understanding ULK1 interactions with proteins like AMPK in these contexts could offer advancements in therapeutic approaches.

Target data

Serine/threonine-protein kinase involved in autophagy in response to starvation (PubMed : 18936157, PubMed : 21460634, PubMed : 21795849, PubMed : 23524951, PubMed : 25040165, PubMed : 29487085, 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). Also phosphorylates SESN2 and SQSTM1 to regulate autophagy (PubMed : 25040165, PubMed : 37306101). 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). Phosphorylates ATG4B, leading to inhibit autophagy by decreasing both proteolytic activation and delipidation activities of ATG4B (PubMed : 28821708).
