PSMB4 is a member of the peptidase T1B family. The 20S Proteasome chamber holds structural alpha subunits and predominantly catalytic beta subunits. The two external rings in the proteasome contain seven alpha subunits each and the two internal rings contain of seven beta subunits each. PSMB4 is a beta subunit of the 20S Proteasome that is spread all over the eukaryotic cells in large quantities and cleaves peptides in an ATP/ubiquitin-dependent process in a non-lysosomal pathway.
PSMB4 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 240 amino acids (46-264 a.a.) and having a molecular mass of 26.6kDa.PSMB4 is fused to a 21 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
| UniProt Protein Function: | PSMB4: a proteasomal protein of the T1B peptidase family. The proteasome is a multicatalytic proteinase complex which is characterized by its ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or slightly basic pH. Proteasomes are distributed throughout eukaryotic cells at a high concentration and cleave peptides in an ATP/ubiquitin-dependent process in a non-lysosomal pathway. |

| NCBI Summary: | 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. [provided by RefSeq, Jul 2008] |
