Psmb9 Gene Summary [Mouse]

Predicted to enable endopeptidase activity and proteasome binding activity. Acts upstream of or within antigen processing and presentation and response to bacterium. Part of proteasome core complex and spermatoproteasome complex. Is expressed in thymus primordium. Human ortholog(s) of this gene implicated in autoimmune disease (multiple); lymphoma; and renal cell carcinoma. Orthologous to human PSMB9 (proteasome 20S subunit beta 9).

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Psmb9 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
