Abstract

Hemin, in concentrations which stimulate protein synthesis and stabilize polyribosomes in reticulocytes, is a potent inhibitor of ribonuclease activity in the erythroid cell. This may offer a partial explanation for the way in which hemin acts to accelerate globin synthesis and thus synchronize the synthesis of hemin and globin in the maturing erythroid cell.
