The “core autophagy machinery” controls the initiation and growth of the autophagosome and has been divided into three main protein groups:
i. A-ATG9, B-TOR, C-PI(3) Complex
ii. A- ATG9, B-PI(3) Complex, C-TOR
iii. The TOR kinase complex acts as a negative regulator of autophagy
iv. The TOR kinase complex acts as a positive regulator of autophagy
