Irf3 Gene Summary [Mouse]
Enables DNA-binding transcription factor activity, RNA polymerase II-specific; identical protein binding activity; and promoter-specific chromatin binding activity. Involved in positive regulation of macromolecule biosynthetic process; response to virus; and type I interferon-mediated signaling pathway. Acts upstream of or within several processes, including lipopolysaccharide-mediated signaling pathway; regulation of defense response; and response to exogenous dsRNA. Located in nucleus. Is expressed in several structures, including central nervous system; early conceptus; eye; and genitourinary system. Human ortholog(s) of this gene implicated in brain disease. Orthologous to human IRF3 (interferon regulatory factor 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 mouse Irf3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
