Rrn3 Gene Summary [Mouse]
Enables RNA polymerase binding activity. Acts upstream of or within several processes, including negative regulation of intrinsic apoptotic signaling pathway by p53 class mediator; regulation of DNA-templated transcription; and transcription initiation at RNA polymerase I promoter. Predicted to be located in nucleolus. Predicted to be active in nucleus. Used to study Parkinson's disease. Orthologous to several human genes including RRN3 (RRN3 homolog, RNA polymerase I transcription factor). [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 Rrn3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
