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.
CC -!- SUBUNIT: Component of the 19S regulatory particle (RP/PA700) base
CC subcomplex of the 26S proteasome. The 26S proteasome is composed of a
CC core protease (CP), known as the 20S proteasome, capped at one or both
CC ends by the 19S regulatory particle (RP/PA700). The RP/PA700 complex is
CC composed of at least 17 different subunits in two subcomplexes, the
CC base and the lid, which form the portions proximal and distal to the
CC 20S proteolytic core, respectively. {ECO:0000269|PubMed:14623884,
CC ECO:0000269|PubMed:20516081}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=1;
CC Comment=A number of isoforms are produced. According to EST
CC sequences.;
CC Name=1;
CC IsoId=Q9MAK9-1; Sequence=Displayed;
CC -!- SIMILARITY: Belongs to the AAA ATPase family. {ECO:0000305}.
