Target description: | Proteasome subunit b type-2 (P49721; also known as EC:3.4.25.1, Macropain subunit C7-I, Multicatalytic endopeptidase complex subunit C7-I, Proteasome component C7-I) is encoded by the PSMB2 gene (Gene ID: 5690) in human. Proteasomes are large multi-subunit protease complexes, localized in the nucleus and cytosol that selectively degrade intracellular proteins. Proteasome consists of a multi-component enzymatic complex known as the 26S proteasome, which 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. The proteolytic core of this complex, the 20S proteasome, contains multiple peptidase activities and functions as the catalytic machine. Unlike other proteases, the 20S proteasome ensures that virtually all peptide bonds within a protein substrate are susceptible to cleavage, by possessing multiple proteolytic activities in one proteolytic internal chamber. This core is composed of 28 subunits arranged in four heptameric, tightly stacked, rings ( 7, β7, β7, 7) to form a cylindrical structure. The proteolytic activity is confined to the β1, β2, and β5-subunits. The proteolytic sites are formed by N-terminal threonine residues that face the central cavity of the 20S complex. The regulatory unit of the 26S proteasome is known as the 19S (PA 700) particle and consists of at least 15 subunits that include ATPases, a de-ubiquitinating enzyme, and polyubiquitin-binding subunits. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals. |
