Vps35p is a peripheral membrane protein (~80% associates with a membranous particulate fraction) required for vacuolar protein sorting; vps35 null mutants quantitatively missort and secrete carboxypeptidase Y (CPY) but retain most PrA, PrB, and ALP, indicating alternative sorting pathways exist for different vacuolar hydrolases. |

Vps35p, together with Vps29p and Vps30p, is required for retrieval of the vacuolar sorting receptor Vps10p from the prevacuolar endosome back to the Golgi; loss of VPS35 shifts Vps10p from the Golgi to the vacuolar membrane via a Pep12p-dependent (pre-vacuolar endosomal t-SNARE) but Sec1p-independent route; Vps35p co-fractionates with Vps10p even in vps29 mutants, suggesting direct interaction. |
