Sorting nexin involved in the separation or division of vacuoles throughout the entire life cycle of the cells (By similarity). Involved in retrieval of late-Golgi SNAREs from post-Golgi endosomes to the trans-Golgi network, for cytoplasm to vacuole transport (Cvt), mitophagy, and pexophagy (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 ATG20 and ATG17 (By similarity). Endosome and other perivacuolar punctate structures (By similarity). Associates to phosphatidylinositol 3-phosphate, necessary for peripheral membrane localization to the perivacuolar punctate structures (By similarity). The PX domain binds phosphatidylinositol 3-phosphate which is necessary for peripheral membrane localization to the perivacuolar punctate structures. Significantly decreases the radial growth of colonies under nutrient-rich conditions (PubMed:28894236). Strongly reduces conidiation (PubMed:28894236). Causes only mild infection in point-inoculated spikelets of flowering wheat heads and impairs the spreading to nearby spikelets (PubMed:28894236). Belongs to the sorting nexin family.
