Interaction between polyuridylic acid and rabbit globin messenger ribonucleic acid.

J A Hunt

    The Biochemical Journal
    |February 1, 1973
    PubMed
    Summary

    Poly(U) binds to globin mRNA, revealing polyadenylate-rich sequences of 30-40 adenylate residues. These homogenous sequences are found in both alpha- and beta-globin mRNA, likely at the 3' terminus.

    Area of Science:

    • Molecular Biology
    • Biochemistry
    • RNA Research

    Background:

    • Globin messenger RNA (mRNA) plays a crucial role in protein synthesis.
    • Understanding mRNA structure and sequence is vital for comprehending gene expression.

    Purpose of the Study:

    • To investigate the interaction between Poly(U) and globin mRNA.
    • To identify and characterize polyadenylate-rich sequences within globin mRNA.

    Main Methods:

    • Binding studies using Poly(U) and globin mRNA in 0.1m-NaCl.
    • Ribonuclease digestion of the Poly(U)-globin mRNA complex.

    Main Results:

    • Poly(U) was observed to bind to globin mRNA.
    • Evidence suggests the presence of homogenous polyadenylate-rich sequences (30-40 adenylate residues) in globin mRNA.
    • These sequences are present in both alpha- and beta-globin mRNA.

    Conclusions:

    • The identified polyadenylate-rich sequences are likely located at the 3' terminus of globin mRNA molecules.
    • These findings contribute to the understanding of globin mRNA structure and potential regulatory elements.
