Recruits the lipid transfer protein VPS13 to endosomal and vacuolar membranes. Interacts (via PxP motif) with VPS13 (via SHR-BD domain) (PubMed:30018089). Interacts with RBD2 (PubMed:15263065). Interacts with YIF1 (PubMed:15263065). Interacts with YIP1 (PubMed:15263065). Interacts with YIP4 (PubMed:15263065). Localizes to nuclear envelope-vacuole contact sites during respiration. The PX domain binds phosphatidylinositol 3-phosphate (PtdIns(3)P) which is necessary for peripheral membrane localization. Decreases VPS13 levels at endosomal membranes and nuclear envelope-vacuole contact sites. Belongs to the YPT35 family.
