Function
Transferrin or serotransferrin (TF) is an iron-binding protein. TF delivers iron from absorption centers in the duodendum and white blood cell macrophages to all tissues[1]. Ovotransferrin (OTF) is a glycosylated TF of egg white. For details see Molecular Playground/Transferrin.
Relevance
Carbohydrate-deficient TF may help diagnose alcoholic liver disease[2].
Structural highlights
TF contains : at the N and C termini. The Fe+3 ion is coordinated to several side chains belonging to both N- and C-lobe, carbonate and sulfate ions[3].
