WebAutophagy requires a direct association between Atg1 and Atg13, and is inhibited by TOR-dependent phosphorylation of Atg13 under high-nutrient conditions (5). Similarly, mammalian Atg13 forms a complex with the Atg1 homologues ULK1/2, along with FIP200, which localizes to autophagic isolation membranes and regulates autophagosome … WebApr 2, 2013 · Autophagy-related 13 (Atg13) is a key early-acting factor in autophagy and the major locus for nutrient-dependent regulation of autophagy by Tor. The 2.3-Å resolution crystal structure of the N-terminal domain of Atg13 reveals a previously unidentified HORMA (Hop1p, Rev1p and Mad2) domain similar to that of the spindle checkpoint protein Mad2.

WebApr 1, 2010 · Rapamycin, an inhibitor of (m)TOR can activate autophagy even under nutrient rich conditions. Rapamycin treatment rapidly induces Atg13 dephosphorylation and promotes Atg1–Atg13–Atg17 complex formation in yeast [13••, 22•]. However, it remains unknown whether Tor directly phosphorylates Atg13. WebDec 7, 2009 · Atg13 is phosphorylated in a Tor-dependent manner, and when isolated from cells under nutrient-rich conditions, Atg13 migrates more slowly by SDS-PAGE, suggesting … mini cooper bluetooth upgrade 2005 https://grandmaswoodshop.com

Tor directly controls the Atg1 kinase complex to regulate …

WebATG13 forms a complex with ULK1 and ULK2, the mammalian homologs of ATG1, and with FIP200. This complex is a target of TOR phosphorylation under normal conditions; inhibition of TOR by rapamycin or leucine deprivation leads to dephosphorylation of ATG13, ULK1 and ULK2, which then leads to autophagy. WebSep 2, 2024 · In yeast, TOR is a key negative regulator that phosphorylates ATG13 under nutrient-rich conditions and reduces the affinity of ATG1 for ATG13. However, nutrient starvation inactivates TOR, allowing ATG13 to become dephosphorylated and the ATG1–ATG13 complex to form and initiate autophagy (Rabinowitz and White, 2010).
