ULK1 is an enzyme that in humans is encoded by the ULK1 gene. Unc-51 like autophagy activating kinase (ULK1/2) are two similar isoforms of an enzyme that in humans are encoded by the ULK1/2 genes. It is specifically a kinase that is involved with autophagy, particularly in response to amino acid withdrawal. Ulk1/2 is an important protein in autophagy for mammalian cells, and is homologous to ATG1 in yeast. It is part of the ULK1-complex, which is needed in early steps of autophagosome biogenesis. The ULK1 complex also consists of the FAK family kinase interacting protein of 200 kDa (FIP200 or RB1CC1) and the HORMA (Hop/Rev7/Mad2) domain-containing proteins ATG13 and ATG101. ULK1, specifically, appears to be the most essential for autophagy and is activated under conditions of nutrient deprivation by several upstream signals which is followed by the initiation of autophagy. However, ULK1 and ULK2 show high functional redundancy; studies have shown that ULK2 can compensate for the loss of ULK1. Nutrient dependent autophagy is only fully inhibited if both ULK1 and ULK2 are knocked out.
