ULK2 (also known as Unc51.2, unc-51 like autophagy activating kinase 2) is a serine/threonine protein kinase that plays a critical role during the initial stages of autophagy in response to nutrient starvation. Mammalian ATG13 binds ULK2 and mediates the interaction of the ULK protein with FIP200. The binding of ATG13 stabilizes and activates ULK and facilitates the phosphorylation of FIP200 by ULK. The ULK-ATG13-FIP200 complex is a direct target of mTOR and an important regulator of autophagy in response to mTOR signaling (1). Yeast 2-hybrid assays showed that the C-terminus of ULK2 binds the C-terminus of SynGAP, a negative regulator of Ras that is associated with neural development (2). Alterations in ULK signaling pathways may be involved in the formation of autophagy-regulated Lewi bodies, which have been associated with Parkinson’s disease (3).
