Probable sterol 3-beta-glucosyltransferase that mediates autophagic degradation of peroxisomes (pexophagy) (PubMed:19363139). Also required for cytoplasm to vacuole transport (Cvt) and autophagic degradation of mitochondria (mitophagy) and nuclei (nucleophagy) (By similarity). However, is not essential for nonselective autophagy (By similarity). Involved pathogenesis via peroxisome degradation inside appressoria that are developing into the host invasion stage (PubMed:19363139). a sterol + UDP-alpha-D-glucose = a sterol 3-beta-D-glucoside + H(+) + UDP The GRAM and PH domains are infection-related pexophagy (PubMed:19363139). Leads to delayed autophagic degradation of peroxisomes in the appressoria (PubMed:19363139). Belongs to the glycosyltransferase 28 family.
