In rats fasted for 24–30 hours, albumin mRNA sequences are released from membrane-bound polysomes to enter the free cytosol fraction. A significant portion of these sequences are present in albumin mRNPs, distinguished from free albumin mRNA and 40S subunit complexes by Cs2SO4equilibrium density centrifugation. Refeeding a mixture of 20 amino acids restores albumin mRNA to membrane-bound polysomes, demonstrating the importance of amino acid supply in the mRNP-polysome equilibrium and in regulation of albumin synthesis.
