The ULK (UNC51-like) enzymes are a family of mammalian kinases that have critical roles in autophagy and development. ULK1 through ULK4 and STK36 are the 5 genes that make up the ULK family of kinases in mammals. It has been established that ULK1 and ULK2 play important roles in a variety of pathological, physiological, and developmental processes in mammals and are required for the proper induction of autophagy.
Serine/threonine protein kinases ULK1 and ULK2, which play redundant roles in the control of autophagy, are evolutionarily conserved orthologs of the yeast member of the Atg (autophagy related) family Atg1. Long-lived proteins or organelles are the targets of autophagy, which degrades them in lysosomes before recycling the byproducts for use in other cellular pathways. The four components of the RB1CC1/FIP200/ATG17, ULK1, ATG13, and ATG101 make up the canonical ULK/ATG1 complex.
By phosphorylating certain enzymes in the class III phosphatidylinositol 3-kinase complex (such as PI3K3C/Vps34, PIK3R4/Vps15, BECN1/Vps30/ATG6, ATG14), it helps to start the formation of autophagosomes, at least in part. Through ATG9, ULK/Atg1 also encourages membrane recycling. Mice lacking both ULK1 and ULK2 expression die soon after birth due to a defect in glycogen metabolism, similar to other autophagy-defective mice, which is consistent with the known role of ULK1/2 in autophagy. Disrupting ULK1 expression also causes a defect in the autophagy-mediated clearance of mitochondria during red blood cell maturation in mice.
