Unconjugated Rabbit anti-Human, Mouse, Rat ATG1(Ser556) Polyclonal Antibody [IgG]

ATG1; ATG1A; UNC51; hATG1; Unc51.1; Serine/threonine-protein kinase ULK1; Autophagy-related protein 1 homolog; Unc-51-like kinase 1; ULK1; KIAA0722

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 negative regulator of mammalian target of rapamycin complex 1 (mTORC1) via interaction with RPTOR. Activated via phosphorylation by AMPK and also acts as a regulator of AMPK by mediating phosphorylation of AMPK subunits PRKAA1, PRKAB2 and PRKAG1, leading to negatively regulate AMPK activity. May phosphorylate ATG13/KIAA0652 and RPTOR; however such data need additional evidences. Plays a role early in neuronal differentiation and is required for granule cell axon formation.
