ULK2 (Q8IYT8) - Overview - Molecular Target Synopsis


ULK2, Serine/threonine-protein kinase ULK2
Enzyme Classification
UniProt Q8IYT8

Also Known as ULK2_HUMAN, ULK2, KIAA0623

Serine/threonine-protein kinase involved in autophagy in response to starvation. Acts upstream of phosphatidylinositol 3-kinase PIK3C3 to regulate the formation of autophagophores, the precursors of autophagosomes. Part of regulatory feedback loops in autophagy: acts both as a downstream effector and a negative regulator of mammalian target of rapamycin complex 1 (mTORC1) via interaction with RPTOR. Activated via phosphorylation by AMPK, also acts as a negative regulator of AMPK through phosphorylation of the AMPK subunits PRKAA1, PRKAB2 and PRKAG1. May phosphorylate ATG13/KIAA0652, FRS2, FRS3 and RPTOR; however such data need additional evidences. Not involved in ammonia-induced autophagy or in autophagic response of cerebellar granule neurons (CGN) to low potassium concentration. Plays a role early in neuronal differentiation and is required for granule cell axon formation: may govern axon formation via Ras-like GTPase signaling and through regulation of the Rab5-mediated endocytic pathways within developing axons. Interacts with SYNGAP1 (By similarity). Component of a complex consisting of ATG13/KIAA0652, ULK1 and RB1CC1/FIP200. Interacts (via C-terminus) with ATG13/KIAA0652. Associates with the mammalian target of rapamycin complex 1 (mTORC1) through an interaction with RPTOR.
