In yeast, 15 Apg proteins coordinate the formation of autophagosomes. Autophagy is a bulk degradation process induced by starvation in eukaryotic cells [1]. Apg6/Vps30p has two distinct functions in the autophagic process, either associated with the membrane or in a retrieval step of the carboxypeptidase Y sorting pathway [2]. This entry is the Beta-Alpha repeated, autophagy-specific (BARA) domain [3].	Domain
