  • Title: In vivo incorporation of ribosomal proteins into HeLa cell ribosomal particles.
    Author: Aiello LO, Goldenberg CJ, Eliceiri GL.
    Journal: Biochim Biophys Acta; 1977 Apr 19; 475(4):652-8. PubMed ID: 856279.
    Abstract:
    Using high salt-washed ribosomal subunits from HeLa cells we detect three ribosomal proteins from the small subunit and five ribosomal proteins from the large subunit that enter ribosomal particles in the absence of ribosome formation (actinomycin D-treated cells); in untreated cells, they enter the ribosomal particles quickly, while the rest of the ribosomal proteins are incorporated gradually. At least two of the large subunit actinomycin D-resistant ribosomal proteins seem to be absent in the 55 S nucleolar ribosomal precursor.
