研究背景

功能:

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. May also phosphorylate SESN2 and SQSTM1 to regulate autophagy.

翻译修饰:

Autophosphorylated. Phosphorylated under nutrient-rich conditions; dephosphorylated during starvation or following treatment with rapamycin. Under nutrient sufficiency, phosphorylated by MTOR/mTOR, disrupting the interaction with AMPK and preventing activation of ULK1 (By similarity). In response to nutrient limitation, phosphorylated and activated by AMPK, leading to activate autophagy.

Acetylated by KAT5/TIP60 under autophagy induction, promoting protein kinase activity.

细胞定位:

Cytoplasm>Cytosol. Preautophagosomal structure.
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.

组织特异性:

Ubiquitously expressed. Detected in the following adult tissues: skeletal muscle, heart, pancreas, brain, placenta, liver, kidney, and lung.

亚基结构:

Interacts with GABARAP and GABARAPL2. Interacts (via C-terminus) with ATG13. Part of a complex consisting of ATG13, ATG101, ULK1 and RB1CC1. Associates with the mammalian target of rapamycin complex 1 (mTORC1) through an interaction with RPTOR; the association depends on nutrient conditions and is reduced during starvation. Interacts with FEZ1; SCOC interferes with FEZ1-binding. Interacts with TBC1D14. Interacts (phosphorylated form) with TRIM5. When phosphorylated at Ser-317, interacts with MEFV and BECN1 simultaneously. Interacts with TRIM21 and IRF3, in the presence of TRIM21. Interacts with SESN2. Interacts with SQSTM1. Interacts with C9orf72. Interacts with WDR45.

蛋白家族:

Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. APG1/unc-51/ULK1 subfamily.
