OX NCBI_TaxID=6239; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=Bristol N2; RX PubMed=9851916; DOI=10.1126/science.282.5396.2012; RG The C. elegans sequencing consortium; RT "Genome sequence of the nematode C. elegans: a platform for investigating RT biology."; RL Science 282:2012-2018(1998). CC -!- FUNCTION: Non-catalytic component of the proteasome, a multicatalytic CC proteinase complex which is characterized by its ability to cleave CC peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group CC at neutral or slightly basic pH. The proteasome has an ATP-dependent CC proteolytic activity (By similarity). {ECO:0000250}. CC -!- SUBUNIT: The 26S proteasome consists of a 20S proteasome core and two CC 19S regulatory subunits. The 20S proteasome core is composed of 28 CC subunits that are arranged in four stacked rings, resulting in a CC barrel-shaped structure. The two end rings are each formed by seven CC alpha subunits, and the two central rings are each formed by seven beta CC subunits. The catalytic chamber with the active sites is on the inside CC of the barrel (By similarity). {ECO:0000250}. CC -!- INTERACTION: CC Q23237; O62102: pbs-2; NbExp=5; IntAct=EBI-314040, EBI-317386; CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|PROSITE-ProRule:PRU00809}. CC Nucleus {ECO:0000250}. CC -!- SIMILARITY: Belongs to the peptidase T1B family. {ECO:0000255|PROSITE- CC ProRule:PRU00809}.
