Serine/threonine-protein kinase ULK1 is an enzyme that in humans is encoded by the ULK1 gene.[3][4]


ULK1 is an important protein in autophagy. It is part of the ULK1-complex, which is needed in early steps of autophagosome biogenesis.


ULK1 has been shown to interact with GABARAPL2,[5] GABARAP,[5][6] SYNGAP1[7] and SDCBP.[7]
