Human interferons: structure and function.

Other relevant areas of research regarding the structure and function of IFNs include the study of IFN fragments and hybrid IFN molecules prepared by recombinant DNA technology, and monoclonal antibodies against IFNs have also made major contributions to our knowledge of IFN structure and function. However, these topics have been addressed in a number of recent reviews (Zoon and Wetzel, 1984; Langer and Pestka, 1985). We are now awaiting the crystal structure of several human IFNs. Once this knowledge has been acquired, we can proceed to envisage at the three-dimensional level how these molecules interact with their receptors to produce their numerous biological activities.
