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
