In contrast to … WebMar 2, 2005 · Atg13 was hyperphosphorylated in a Tor-dependent manner in rich medium conditions. This form of Atg13 has a low affinity for Atg1 (Figure 2, lane 1; Kamada et al., 2000). Rapamycin treatment, which inhibits Tor, resulted in dephosphorylation of Atg13, and dephosphorylated Atg13 showed a higher affinity for Atg1 (Figure 2, lane 3).

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. WebMar 1, 2014 · Inhibitory phosphorylation of Atg13 reflects the activity of TOR complex 1 (TORC1) and protein kinase A. Accordingly, monitoring the phosphorylation state of Atg13 provides a convenient way to follow early steps of autophagy induction as well as the activity of some of the upstream nutrient-sensing kinases. However, the detection of …
