CRYTAL STRUCTURE OF THE ECTODOMAIN OF HUMAN TRANSFERRIN RECEPTOR

Overview

The transferrin receptor (TfR) undergoes multiple rounds of, clathrin-mediated endocytosis and reemergence at the cell surface, importing iron-loaded transferrin (Tf) and recycling apotransferrin after, discharge of iron in the endosome. The crystal structure of the dimeric, ectodomain of the human TfR, determined here to 3.2 angstroms resolution, reveals a three-domain subunit. One domain closely resembles carboxy- and, aminopeptidases, and features of membrane glutamate carboxypeptidase can, be deduced from the TfR structure. A model is proposed for Tf binding to, the receptor.
