Ubr1 Gene Summary [Mouse]
Enables ubiquitin protein ligase activity. Involved in ubiquitin-dependent protein catabolic process via the N-end rule pathway. Acts upstream of or within ubiquitin-dependent protein catabolic process. Part of proteasome complex and ubiquitin ligase complex. Is expressed in several structures, including branchial arch; genitourinary system; limb bud; liver; and lung. Used to study Johanson-Blizzard syndrome. Human ortholog(s) of this gene implicated in Johanson-Blizzard syndrome and cardiovascular system disease. Orthologous to human UBR1 (ubiquitin protein ligase E3 component n-recognin 1).

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 Ubr1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
