Interferon regulatory factors (IRF) are proteins which regulate transcription of interferons (see regulation of gene expression). [1] Interferon regulatory factors contain a conserved N-terminal region of about 120 amino acids, which folds into a structure that binds specifically to the IRF-element (IRF-E) motifs, which is located upstream of the interferon genes.

Interferon regulatory factor 5 is a protein that in humans is encoded by the IRF5 gene. [5] The IRF family is a group of transcription factors that are involved in signaling for virus responses in mammals along with regulation of certain cellular functions.
Interferon regulatory factor 8 (IRF8) also known as interferon consensus sequence-binding protein (ICSBP), is a protein that in humans is encoded by the IRF8 gene. [5] [6] [7] IRF8 is a transcription factor that plays critical roles in the regulation of lineage commitment and in myeloid cell maturation including the decision for a common myeloid progenitor (CMP) to differentiate into a ...

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.
Interferon regulatory factor 1 was the first member of the interferon regulatory transcription factor (IRF) family identified. Initially described as a transcription factor able to activate expression of the cytokine Interferon beta, [6] IRF-1 was subsequently shown to function as a transcriptional activator or repressor of a variety of target genes.
MAVS activation leads to the increased levels of pro-inflammatory cytokines via activation of transcription factors, nuclear factor kB , interferon regulatory factor 1 , and interferon regulatory factor 3 . [7] [8] [9] NF-κB, IRF1, and IRF3 are transcription factors and play critical roles in the production of cytokines.
