Identification of an Erythroid Active Element in the Transferrin Receptor Gene

Abstract excerpt

Hemoglobin synthesis consumes most of the iron that is taken up by cells from plasma transferrin, and this process requires very high expression of transferrin receptors (TfR) at the membranes of erythroid cells. Studies in our and other laboratories indicate that a dramatic increase in TfR levels during erythroid differentiation occurs at the transcriptional level. In this study, we investigated the...
