Transferrin

Transferrin (TF; 79 kDa; SIDERO domain) is the plasma iron-transport protein; binds Fe³⁺ with Kd ~10⁻²⁰ M at pH 7.4; TFR1/CD71-mediated endocytosis delivers iron to erythroid precursors; TSAT and ferritin together diagnose iron deficiency anemia vs iron overload.

Also known as: transferrin, TF, serotransferrin, siderophilin, TSAT, transferrin saturation, iron-binding protein, TFR1, transferrin receptor
