Table 2. Atg/ATG proteins in the core machinery of autophagosome formation.

  Yeast Mammals Characteristics and functions
Atg1/ULK complex
Atg1 ULK1/2 Ser/Thr protein kinase; phosphorylated by M/TORC1; recruitment of Atg proteins to the PAS
Atg13 ATG13 Regulatory subunit through phosphorylation by M/TORC1 and/or PKA, linker between Atg1 and Atg17
Atg17 RB1CC1/FIP200 (functional homolog) Scaffold protein, ternary complex with Atg29 and Atg31. Phosphorylated by ULK1; scaffold for ULK1/2 and ATG13
Atg29   Ternary complex with Atg17 and Atg31
Atg31   Ternary complex with Atg17 and Atg29
Atg11   Scaffold protein in selective autophagy for PAS organization
