Interferon regulatory factors (IRF) are proteins which regulate transcription of interferons (see regulation of gene expression).[1] They are used in the JAK-STAT signaling pathway.[2] Interferon regulatory factors contain a conserved N-terminal region of about 120 amino acids, which folds into a structure that binds specifically to the interferon consensus sequence (ICS), which is located upstream of the interferon genes.[3] The remaining parts of the interferon regulatory factor sequence vary depending on the precise function of the protein.[3] The Kaposi sarcoma herpesvirus, KSHV,[4] is a cancer virus that encodes four different IRF-like genes;[5] including vIRF1,[6] which is a transforming oncoprotein that inhibits type 1 interferon activity.[7] In addition, the expression of IRF genes is under epigenetic regulation by promoter DNA methylation.
