Bard1 Gene Summary [Rat]
Predicted to enable RNA binding activity; protein heterodimerization activity; and protein homodimerization activity. Predicted to contribute to ubiquitin-protein transferase activity. Involved in several processes, including cellular response to follicle-stimulating hormone stimulus; cellular response to testosterone stimulus; and response to aldosterone. Predicted to be located in cytoplasmic ribonucleoprotein granule and nuclear speck. Predicted to be part of nucleus. Biomarker of retinal degeneration. Human ortholog(s) of this gene implicated in breast cancer and ovarian cancer. Orthologous to human BARD1 (BRCA1 associated RING domain 1). [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 Bard1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
