    Summary
    Enables guanyl-nucleotide exchange factor activity and small GTPase binding activity. Contributes to phosphatidylinositol binding activity. Involved in several processes, including piecemeal microautophagy of the nucleus; positive regulation of TORC1 signaling; and vacuole fusion, non-autophagic. Located in fungal-type vacuole membrane and vacuole-mitochondrion membrane contact site. Part of HOPS complex. Orthologous to several human genes including VPS39 (VPS39 subunit of HOPS complex).
