  • Title: [Reaction between 125I-collagen and growing fibronectin polypeptides of chick embryo polyribosomes].

    Journal: Vopr Med Khim; 1982; 28(2):108-14. PubMed ID: 7080470.
    Abstract:
    Polyribosomes from chicken embryos and 125I-collagen were shown to form complexes, which might be isolated from free 125I-collagen by means of centrifugation. The fraction of rapidly sedimenting polyribosomes was the most active in formation of complexes with 125I-collagen. The complexes ribosomes-125I-collagen appeared after destruction of polyribosomes-125I-collagen complexes by means of RNAase. Treatment of the complexes with puromycine led to liberation of about 40% of 125I-collagen. Antibodies against fibronectin inhibited the complex formation by about 30%. The data obtained suggest that the growing fibronectin polypeptides participate in formation of at least 30% of the complexes.
