General description

Transferrin is a glycoprotein with a branched carbohydrate chain, having two sites for ferric ion binding in its polypeptide chain.

Application

Transferrin human has been used:
  • to incubate human proximal tubule cells (HKC) - 8 cells along with IgG for the examination of albumin specificity
  • as a supplement in serum-containing/devoid medium for human thyroid cell culture
  • as a target glycoprotein to develop an in-gel hydrazinolysis method

Biochem/physiol Actions

Transferrin mediates iron transportation from plasma to cells. The iron-bound transferrin are of three forms: monoferric A/B transferrin and diferric transferrin. The transferrin binds to specific cell surface receptors and are internalized by endocytosis. Once inside, the iron is released into the cells and the iron-free transferrin, also referred to as apotransferrin, is exocytosed outside the cell without being degraded. Transferrin is known to deliver iron to cells in a physiologically safe and effective form.

  5. What is the carbohydrate content of human transferrin?

    We have found the information on transferrin in a reference book:The Plasma Proteins, F.W. Putnam, ed, volume 2, chapter 4, Table II.According to the table, Transferrin is 6 percent carbohydrate, citing G.A. Jamieson, J. Biol. Chem. 240(7), 2914-2920 (1965).The table also gives information on the percentage of each type of monosaccharide that is present.
