CC   -!- FUNCTION: The proteasome is a multicatalytic proteinase complex which
CC       is characterized by its ability to cleave peptides with Arg, Phe, Tyr,
CC       Leu, and Glu adjacent to the leaving group at neutral or slightly basic
CC       pH. The proteasome has an ATP-dependent proteolytic activity. Mediates
CC       the association of the SCF(TIR1) E3 ubiquitin ligase complex with the
CC       proteasome. {ECO:0000269|PubMed:11387208}.
CC   -!- SUBUNIT: Component of the 20S core complex of the 26S proteasome. The
CC       26S proteasome is composed of a core protease (CP), known as the 20S
CC       proteasome, capped at one or both ends by the 19S regulatory particle
CC       (RP/PA700). The 20S proteasome core is composed of 28 subunits that are
CC       arranged in four stacked rings, resulting in a barrel-shaped structure.
CC       The two end rings are each formed by seven alpha subunits, and the two
CC       central rings are each formed by seven beta subunits. The catalytic
CC       chamber with the active sites is on the inside of the barrel. Interacts
CC       with KIN10 and KIN11 SnRK subunits, and with the SKP1A/ASK1 subunit of
CC       the SCF E3 ubiquitin ligase complex. {ECO:0000269|PubMed:10363660,
CC       ECO:0000269|PubMed:11387208, ECO:0000269|PubMed:14623884,
CC       ECO:0000269|PubMed:20516081}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus
CC       {ECO:0000269|PubMed:11387208}.
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=P30186-1; Sequence=Displayed;
CC   -!- TISSUE SPECIFICITY: Expressed in roots, leaves and flowers.
CC       {ECO:0000269|PubMed:1516703}.
CC   -!- INDUCTION: During cell proliferation. {ECO:0000269|PubMed:7987412}.
CC   -!- SIMILARITY: Belongs to the peptidase T1A family. {ECO:0000255|PROSITE-
CC       ProRule:PRU00808}.
