Recombinant Human Proteasome (Prosome, Macropain) Subunit, Beta Type, 3, His-tagged

Cat. No.: PSMB3-1540H
Product Overview: Recombinant human PSMB3 protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.
Description: The proteasome is a multicatalytic proteinase complex with a highly ordered ring-shaped 20S core structure. The core structure is composed of 4 rings of 28 non-identical subunits; 2 rings are composed of 7 alpha subunits and 2 rings are composed of 7 beta subunits. Proteasomes are distributed throughout eukaryotic cells at a high concentration and cleave peptides in an ATP/ubiquitin-dependent process in a non-lysosomal pathway. An essential function of a modified proteasome, the immunoproteasome, is the processing of class I MHC peptides

Molecular Weight: 25.1 kDa (225aa), confirmed by MALDI-TOF
Purity: > 90% by SDS - PAGE
