-!- FUNCTION: Component of the 20S core proteasome complex involved in
the proteolytic degradation of most intracellular proteins. This
complex plays numerous essential roles within the cell by
associating with different regulatory particles. Associated with
two 19S regulatory particles, forms the 26S proteasome and thus
participates in the ATP-dependent degradation of ubiquitinated
proteins. The 26S proteasome plays a key role in the maintenance
of protein homeostasis by removing misfolded or damaged proteins
that could impair cellular functions, and by removing proteins
whose functions are no longer required. Associated with the PA200
or PA28, the 20S proteasome mediates ubiquitin-independent protein
degradation. This type of proteolysis is required in several
pathways including spermatogenesis (20S-PA200 complex) or
generation of a subset of MHC class I-presented antigenic peptides
(20S-PA28 complex). {ECO:0000269|PubMed:15244466,
ECO:0000269|PubMed:27176742, ECO:0000269|PubMed:8610016}.
-!- CATALYTIC ACTIVITY: Cleavage of peptide bonds with very broad
specificity. {ECO:0000255|PROSITE-ProRule:PRU00808,
ECO:0000269|PubMed:27176742}.
-!- SUBUNIT: The 26S proteasome consists of a 20S proteasome core and
two 19S regulatory subunits. The 20S proteasome core is a barrel-
shaped complex made of 28 subunits that are arranged in four
stacked rings. The two outer rings are each formed by seven alpha
subunits, and the two inner rings are formed by seven beta
subunits. The proteolytic activity is exerted by three beta-
subunits PSMB5, PSMB6 and PSMB7. {ECO:0000269|PubMed:25599644,
ECO:0000269|PubMed:26133119, ECO:0000269|PubMed:27342858,

protein level). {ECO:0000269|PubMed:11521686,

for nuclear import. {ECO:0000250}.
-!- SIMILARITY: Belongs to the peptidase T1A family.
