    Area of Science:

    • Biochemistry
    • Immunology
    • Molecular Biology

    Background:

    • Significant advances in interferon purification have been achieved in recent years.
    • Human and mouse interferon components have been purified to homogeneity, enabling partial characterization.

    Purpose of the Study:

    • To detail the structural characterization of purified interferons.
    • To investigate the role of the carbohydrate portion in interferon species specificity.
    • To establish interrelationships within the interferon protein family.

    Main Methods:

    • Purification of human and mouse interferons to homogeneity.
    • Partial characterization including amino acid composition and peptide mapping.
    • Analysis of amino-terminal amino acid sequences.

    Main Results:

    • Homogeneous interferon components from humans and mice have been obtained.
    • Preliminary data suggest carbohydrates influence interferon species specificity.
    • Limited structural information is available due to small quantities of purified interferons.

    Conclusions:

    • Current production and purification methods can yield sufficient material for further structural studies.
    • Detailed structural analysis, including carbohydrate examination and gene characterization, is crucial.
    • New structural data will elucidate the relationships among interferon proteins, especially between human and mouse types.
