Automated description from the Alliance of Genome Resources (Release 3.1.1)
Exhibits ubiquitin-protein transferase activity. Involved in ubiquitin-dependent protein catabolic process. Localizes to 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. Orthologous to human UBR1 (ubiquitin protein ligase E3 component n-recognin 1).
