Plays a role in autophagy (By similarity). Functions at the preautophagosomal structure (PAS) in order to form normal autophagosomes under starvation conditions (By similarity). Also plays a role in mitophagy (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 stable complex with ATG17 and ATG31 (By similarity). Interacts directly with ATG31 (By similarity). The ATG17-ATG29-ATG31 complex interacts with the ATG1-ATG13 complex (By similarity). Note=The interaction with the ATG1-ATG13 complex is induced by starvation (By similarity). Localizes also to other perivacuolar punctate structures (By similarity). Significantly decreases the radial growth of colonies under nutrient-rich conditions (PubMed:28894236). Belongs to the ATG29 family.
