Psmb3 Gene Summary [Mouse]
Predicted to enable endopeptidase activity. Predicted to be involved in proteasome-mediated ubiquitin-dependent protein catabolic process. Predicted to act upstream of or within protein catabolic process. Part of proteasome core complex. Is expressed in several structures, including cranial ganglion; gonad; gut; skin; and tooth. Orthologous to human PSMB3 (proteasome 20S subunit beta 3). [provided by Alliance of Genome Resources, Jul 2025]

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 Psmb3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
