Recombinant Human PSMB1 Protein, Myc/DDK-tagged, C13 and N15-labeled

• Cat.No.: PSMB1-1912H
• Product Overview: PSMB1 MS Standard C13 and N15-labeled recombinant protein (NP_002784) with a C-terminal MYC/DDK tag, was expressed in HEK293 cells.

Specification

• 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. This gene encodes a member of the proteasome B-type family, also known as the T1B family, that is a 20S core beta subunit. This gene is tightly linked to the TBP (TATA-binding protein) gene in human and in mouse, and is transcribed in the opposite orientation in both species.
