NCIt definition : Transferrin receptor protein 1 (760 aa, 85 kDa) is encoded by the human TFRC gene.
This protein plays a role in the transport of iron into cells.;
NCIt note : Transferrin receptor protein 1 acts as a receptor for the new-world arenaviruses,
Guanarito, Junin and Machupo virus. (UniProt); Transferrin receptor protein 1 is cleaved after the arginine residue at position 100
by trypsin to produce the soluble serum form (sTfR).; Transferrin receptor protein 1 is structurally related to the aminopeptidase subfamily
M28B but does not appear to have enzymatic activity. (MEROPS);
