CC   -!- FUNCTION: Probable aspartic protease. May be involved in the regulation
CC       of exocytosis. Acts as a linker between the 19S proteasome and
CC       polyubiquitinated proteins via UBA domain interactions with ubiquitin
CC       for their subsequent degradation. Required for S-phase checkpoint
CC       control. {ECO:0000250|UniProtKB:I7HUG0, ECO:0000250|UniProtKB:P40087}.
CC   -!- SUBUNIT: Binds ubiquitin and polyubiquitinated proteins. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the DDI1 family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=BAE55528.1; Type=Erroneous initiation; Evidence={ECO:0000305};
