UniProtKB description: Aspartic protease (PubMed:21266539). Appears to act as negative regulator of constitutive exocytosis (PubMed:10330187, PubMed:12051757). May act at the level of secretory vesicle docking and fusion as a competitive inhibitor of SNARE assembly (PubMed:12925750). Acts as a linker between the 19S proteasome and polyubiquitinated proteins like the HO endonuclease and UFO1 via UBA domain interactions with ubiquitin for their subsequent degradation (PubMed:16478980, PubMed:17144915). Required for S-phase checkpoint control (PubMed:11238935, PubMed:17144915).
