IRF4 is a transcription factor belonging to the Interferon Regulatory Factor (IRF) family of transcription factors. [8] [9] In contrast to some other IRF family members, IRF4 expression is not initiated by interferons; rather, IRF4 expression is promoted by a variety of bioactive stimuli, including antigen receptor engagement, lipopolysaccharide (LPS), IL-4, and CD40.
