Abstract:
:Free and endoplasmic reticulum-bound polyribosomes from rat heart were examined for their ferritin mRNA content. A procedure for separation and purification of the two ribosome populations that produced good yields of homogeneous mono- and polyribosomes with no contaminating ultrastructures and gave distinctive sedimentation profiles in 15-50% sucrose gradients was developed. 14C-labeled free and bound polyribosomes added to heart preparations indicated that only 3% of free and 5.5% of bound polyribosomes cross-contaminated the bound and free fractions, respectively. RNA from both polyribosome populations hybridized with [32P]cDNA for rat ferritin. The extent of hybridization with mRNA from endoplasmic reticulum (ER)-derived polyribosomes was much greater than what could be accounted for by cross-contamination with free polyribosomes. This indicates that heart ferritin is synthesized not only on free polyribosomes for internal use in iron storage but also on ER-bound polyribosomes, where it may be destined for secretion into the plasma.
