The Band 3 protein is the most abundant integral protein of human erythrocyte membranes and functions as the major anion transporter polypeptide of erythrocytes. Band 3 is a 90-100 kDa protein, its microheterogeneity is ascribed mainly to the structural heterogeneity of the carbohydrate moiety. The C-terminal portion of the molecule spans the membrane several times, and is responsible for anion transport. The N-terminal portion, comprising almost half of the polypeptide chain of Band 3, is located inside the red cell and interacts with cytoskeletal and cytoplasmic proteins such as ankyrin.
