ATG3 is subjected to redox regulation to quarantee ATG8 lipidation under ROS-generating stresses
The conjugation of ATG8 (autophagy-related 8) proteins to the lipid phospha-tidylethanolamine (PE) is the result of the coordinated and highly regulated action of several ATG core proteins, including ATG4 proteases and the E1 (ATG7)- and E2 (ATG3)- activating enzymes. Although it has been stablished...

| Sumario: | The conjugation of ATG8 (autophagy-related 8) proteins to the lipid phospha-tidylethanolamine (PE) is the result of the coordinated and highly regulated action of several ATG core proteins, including ATG4 proteases and the E1 (ATG7)- and E2 (ATG3)- activating enzymes. Although it has been stablished that ROS signaling plays an important role in autophagy activation, the molecular mechanisms underlying the redox control of ATG proteins remain largely unclear. We have recently shown that ATG3 activity in Chlamydomonas rein- hardtii is subjected to reversible redox regulation to ensure ATG8 lipidation and autophagy progression under ROS-linked stress conditions. |
