85-1771-49　PSMB4, Recombinant, Human, aa46-264, His-Tag (Proteasome subunit beta type-4) 250ug　029684

特徴

• PSMB4, belonged to the peptidase T1B family. The 20S Proteasome chamber contains alpha subunits (which are structural) and beta subunits (which are predominantly catalytic). The outer two rings in the proteasome consist of seven alpha subunits each and the inner two rings each consist of seven beta subunits. PSMB4 is a beta subunit of the 20S Proteasome. It is distributed throughout eukaryotic cells at a high concentration and cleaves peptides in an ATP/ubiquitin-dependent process in a non-lysosomal pathway.
• Source:Recombinant corresponding to aa46-264 from human PSMB4, fused to His-tag at N-terminal expressed in E.coli.
