  • Title: Purification and translation of ovalbumin, conalbumin, ovomucoid and lysozyme messenger RNA.
    Author: Palmiter RD, Smith LT.
    Journal: Mol Biol Rep; 1973 Oct; 1(3):129-34. PubMed ID: 24197507.
    Abstract:
    Messenger RNAs for 4 egg white proteins (ovalbumin, conalbumin, ovomucoid and lysozyme) were assayed in a cell-free, protein-synthesizing system derived from rabbit reticulocytes. Each of these messengers was purified about 33-fold from hen oviduct polysomal RNA using oligo(dT) cellulose. The apparent minimal translational efficiencies varied from 22 translations for each ovalbumin mRNA to less than 1 for lysozyme mRNA. These messengers are not polycistronic with each other since they have distinct sedimentation values of: lysozyme, 8.5S; ovomucoid, 11S; ovalbumin, 15S; and conalbumin 18S. Several aspects of this system indicate that it will be valuable for dissecting the fine control of mRNA metabolism.
