General description
Transferrin is a bilobed glycoprotein containing an N-terminal lobe and a C-terminal lobe. Each of these domains is divided into two sub-domains and within the inter subdomain cleft is the metal-binding site. A single transferrin molecule can bind to two ferric ions. Apo-transferrin is an iron-free form.
Application
Biochem/physiol Actions
Transferrin transports iron through receptor-mediated endocytosis. The iron transport mechanism occurs in the endothelial cells of the blood-brain barrier. Transferrin maintains iron homeostasis and is an iron-associated marker. Reduced levels of transferrin are observed in severe COVID-19 conditions. It may bind to other molecules apart from iron, hence it can be used in targeted drug delivery.
Other Notes
Non-heme iron-transport protein.

What is the carbohydrate content of human transferrin?
1 answer-
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.
