    The human alpha-interferon (huIFN-alpha) family displays broad spectrum antiviral, antiproliferative and immunomodulatory activities on a variety of cell types. The diverse biological activities of the IFN-alpha's are conveyed to cells through specific interactions with cell-surface receptors. Despite considerable effort, no crystal structure of a member of this family has yet been reported, because the quality of the protein crystals have been unsuitable for crystallographic studies. Until now, structural models of the IFN-alpha's have been based on the structure of murine IFN-beta (muIFN-beta). These models are likely to be inaccurate, as the amino acid sequence of muIFN-beta differs significantly from the IFN-alpha's at proposed receptor-binding sites. Structural information on a huIFN-alpha subtype would provide an improved basis for modeling the structures of the entire IFN-alpha family.
