Function |
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. {ECO:0000269|PubMed:10624947, ECO:0000269|PubMed:19258318, ECO:0000269|PubMed:21205641, ECO:0000269|PubMed:21258367, ECO:0000269|PubMed:21460634}.

Subcellular Location |
Cytoplasm, cytosol {ECO:0000269|PubMed:19258318}. Preautophagosomal structure {ECO:0000269|PubMed:19258318}. Note=Under starvation conditions, is localized to puncate structures primarily representing the isolation membrane that sequesters a portion of the cytoplasm resulting in the formation of an autophagosome.
