CC   -!- FUNCTION: The 26S proteasome is involved in the ATP-dependent
CC       degradation of ubiquitinated proteins. The regulatory (or ATPase)
CC       complex confers ATP dependency and substrate specificity to the 26S
CC       complex (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}. Nucleus {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the AAA ATPase family. {ECO:0000305}.
