Interferon-β is a protein growth factor that stimulates an antiviral defense. Its encoding gene is one of only two known vertebrate structural genes that lacks introns.<ref name="Biochem Text">Voet, D., Voet, J.G., and C. Pratt. ''Fundamentals of Biochemistry'' 3rd Edition.

Interferon-β is a relatively simple biological response modifier, with several <scene name='Multiple_sclerosis/Interferon_beta_labeled/1'>identifiable regions</scene>. It consists of five <scene name='Multiple_sclerosis/Ifnb_helices_in_color/1'>alpha helices</scene>, as well as multiple interconnecting <scene name='Multiple_sclerosis/Interferon_beta_loops/1'>loops regions</scene>, highlighted in blue.
