Interferon regulatory factors 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]
