WebMar 17, 2024 · Figure 1. The model illustrates the roles of ULK1-ATG13 in the cell cycle and its phospho-regulation and function in mitosis. When cells are in mitosis, CDK1-CCNB/cyclin B phosphorylates ULK1-ATG13 to induce a significant electrophoretic bandshift. The phosphorylated ULK1-ATG13 promotes mitotic autophagy and cell cycle … WebDec 12, 2024 · ULK1’s serine/threonine protein kinase activity is required for starvation-induced autophagy. The mTORC1 pathway is a critical negative regulator of ULK1, and hence autophagy, in response to amino acid availability. The ULK1 complex can regulate selective autophagy and is involved in numerous human pathologies.
