Probable sterol 3-beta-glucosyltransferase that mediates autophagic degradation of peroxisomes (pexophagy) (PubMed:27696999). Also required for cytoplasm to vacuole transport (Cvt) and autophagic degradation of mitochondria (mitophagy) and nuclei (nucleophagy) (PubMed:27696999). a sterol + UDP-alpha-D-glucose = a sterol 3-beta-D-glucoside + H(+) + UDP The GRAM and PH domains are required for the localization of ATG26 to the preautophagosomal structure (PAS) and are involved in autophagy (PubMed:27696999). Leads to white colonies with decreased conidiation and aerial hyphae formation (PubMed:27696999). Impairs autophagy by the accumulation of the intermediate of autophagosome (PubMed:27696999). Belongs to the glycosyltransferase 28 family.
