    Summary

    Cloned DNA for complement proteins like C3 and C4 enables advanced study of their structure, function, and genetics. Research on C2, factor B, and C4 genes highlights links between these complement components and disease susceptibility.

    Area of Science:

    • Immunology
    • Molecular Biology
    • Genetics

    Background:

    • Complement proteins are crucial for innate immunity.
    • Cloned DNA for several complement proteins (C1q, C2, C3, C4, C5, C9, factor B, C4b-binding protein, C1-inhibitor) is available.
    • Understanding these proteins is vital for immunology and disease research.

    Purpose of the Study:

    • To review the impact of cloned complement protein DNA on scientific understanding.
    • To highlight advances in structure, function, biosynthesis, and genetics.
    • To emphasize the connection between specific complement genes and disease susceptibility.

    Main Methods:

    • Isolation of cDNA and genomic clones for complement proteins.
    • Analysis of derived amino acid sequences for structural insights.
    • Genetic studies focusing on C2, factor B, and C4 genes.

    Main Results:

    • Availability of cloned DNA has accelerated research on complement proteins.
    • Detailed understanding of complement protein structure, function, biosynthesis, and genetics has been achieved.
    • Studies on C2, factor B, and C4 genes reveal associations with disease susceptibility.

    Conclusions:

    • Cloned complement protein DNA is a powerful tool for advancing immunological research.
    • Genetic variations in complement genes, particularly C2, factor B, and C4, are linked to disease susceptibility.
    • Further research into complement genetics holds promise for understanding and treating immune-related diseases.
