Involved in cytoplasm to vacuole transport (Cvt), pexophagy, mitophagy and nucleophagy (By similarity). Recruits mitochondria for their selective degradation via autophagy (mitophagy) during starvation, through its interaction with ATG32 (By similarity). Works as scaffold proteins that recruit ATG proteins to the pre-autophagosome (PAS), the site of vesicle/autophagosome formation (By similarity). Required for ATG9 anterograde transport from the mitochondria to the PAS (By similarity). Recruits also the ATG19-prAPE1 complex to the PAS (By similarity). Required for the Cvt vesicles completion (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). Homodimer and potential homooligomers (By similarity). Interacts with ATG1 kinase and the ATG19 and ATG34 cargo protein transporters (By similarity). Interacts with ATG9, ATG17 and ATG20 (By similarity). During pexophagy, accumulates in the vacuolar membrane region, where the peroxisomes contact the vacuole (By similarity). Significantly decreases the radial growth of colonies under nutrient-rich conditions (PubMed:28894236). Strongly reduces conidiation (PubMed:28894236). Belongs to the ATG11 family.
