Nr4a3 Gene Summary [Rat]
Enables several functions, including DNA-binding transcription activator activity, RNA polymerase II-specific; nuclear glucocorticoid receptor binding activity; and protein homodimerization activity. Involved in several processes, including animal organ regeneration; positive regulation of cardiac muscle hypertrophy; and regulation of type B pancreatic cell proliferation. Predicted to be part of transcription regulator complex. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in extraskeletal myxoid chondrosarcoma. Orthologous to human NR4A3 (nuclear receptor subfamily 4 group A member 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 rat Nr4a3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
