Effector of VPS34 phosphatidylinositol 3-phosphate kinase signaling (By similarity). Regulates the cytoplasm to vacuole transport (Cvt) vesicle formation (By similarity). Plays a role in ATG protein retrieval from the pre-autophagosomal structure (PAS) and is especially required for autophagy-dependent cycling of ATG9 (By similarity). Autophagy is required for proper vegetative growth, asexual/sexual reproduction, and full virulence (PubMed:28894236). Autophagy is particularly involved in the biosynthesis of deoxynivalenol (DON), an important virulence determinant (PubMed:28894236). Forms a complex with ATG9 and ATG23 (By similarity). Cycles among the pre-autophagosomal structure (PAS), mitochondria and Golgi (By similarity). Does not significantly decrease the growth rate under nutrient-rich conditions (PubMed:28894236). Belongs to the ATG27 family.
