PSMB7 (human)

PSMB7 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. This catalytic subunit is downregulated by gamma interferon and proteolytic processing is required to generate a mature subunit. Not present in the immunoproteasome and is replaced by catalytic subunit 2i (proteasome beta 10 subunit). Note: This description may include information from UniProtKB.
