OX NCBI_TaxID=10090; RN [1] RP SEQUENCE FROM N.A. RC STRAIN=B10.BR; RX MEDLINE=99367391; PubMed=10436176; RA Elenich L.A., Nandi D., Kent E.A., McCluskey T.S., Cruz M., Iyer M.N., RA Woodward E.C., Conn C.W., Ochoa A.L., Ginsburg D.B., Monaco J.J.; RT "The complete primary structure of mouse 20S proteasomes."; RL Immunogenetics 49:835-842(1999). RN [2] RP SEQUENCE FROM N.A. RA Strausberg R.; RL Submitted (JAN-2001) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: THE PROTEASOME IS A MULTICATALYTIC PROTEINASE COMPLEX CC WHICH IS CHARACTERIZED BY ITS ABILITY TO CLEAVE PEPTIDES WITH ARG, CC PHE, TYR, LEU, AND GLU ADJACENT TO THE LEAVING GROUP AT NEUTRAL OR CC SLIGHTLY BASIC PH. THE PROTEASOME HAS AN ATP-DEPENDENT PROTEOLYTIC CC ACTIVITY. CC -!- CATALYTIC ACTIVITY: Cleavage at peptide bonds with very broad CC specificity. CC -!- PATHWAY: Involved in an ATP/ubiquitin-dependent non-lysosomal CC proteolytic pathway. CC -!- SUBUNIT: THE PROTEASOME IS COMPOSED OF AT LEAST 15 NON IDENTICAL CC SUBUNITS WHICH FORM A HIGHLY ORDERED RING-SHAPED STRUCTURE. CC -!- SUBCELLULAR LOCATION: Cytoplasmic and nuclear. CC -!- SIMILARITY: BELONGS TO PEPTIDASE FAMILY T1A; ALSO KNOWN AS THE CC PROTEASOME A-TYPE FAMILY.
