The yeast YAP3 gene encodes an aspartyl endoprotease that cleaves precursor proteins at selected pairs of basic amino acids and after single arginine residues. Biosynthetic studies of this proprotein processing enzyme indicate that Yap3 is predominantly cell-associated and migrates as a approximately 160-kDa protein on SDS-polyacrylamide gel electrophoresis. Nearly equal amounts of Yap3 are immunodetected in a-haploid, alpha-haploid, and a/alpha-diploid yeast, demonstrating that the expression of YAP3 is not mating type-specific. As shown by endoglycosidase H treatment, which drastically reduces both the estimated molecular mass and the heterogeneity of the protein on SDS-polyacrylamide gel electrophoresis (68 versus 160 kDa), the oligosaccharides N-linked to the protein are subjected to extensive outer chain mannosylation. Outer chain sugar mannosylation takes place in the Golgi apparatus and is commonly found on yeast secreted glycoproteins and/or cell wall mannoproteins. Treatment of the total yeast membranes with chemical agents known to disrupt protein-protein and protein-lipid interactions reveal that Yap3 is membrane-associated. Based upon the release of the membrane-bound form by bacterial phosphatidylinositol phospholipase C digestion and metabolic labeling of the protein with myo-[3H]inositol, Yap3 owes its association with the membrane to the addition of a glycophosphatidylinositol anchor. The cellular localization of Yap3 has been addressed by subcellular fractionation studies. In both differential centrifugation of intracellular organelles and sucrose density gradients, the bulk of Yap3 at steady state co-localizes with the plasma membrane azide-insensitive ATPase. Furthermore, consistent with the transport of Yap3 to the plasma membrane, the endoprotease sediments with secretory vesicles which accumulate at restrictive temperature in the late secretory mutant sec1-1. We therefore conclude that the endoprotease encoded by YAP3 is a glycophosphatidylinositol-anchored protein, which can process substrates both intracellularly and at the cell surface.
