117-724 0e+00

Band 3 cytoplasmic domain; This family contains the cytoplasmic domain of the Band 3 anion exchange proteins that exchange Cl-/HCO3-. Band 3 constitutes the most abundant polypeptide in the red blood cell membrane, comprising 25% of the total membrane protein. The cytoplasmic domain of band 3 functions primarily as an anchoring site for other membrane-associated proteins. Included among the protein ligands of cdb3 are ankyrin, protein 4.2, protein 4.1, glyceraldehyde-3-phosphate dehydrogenase (GAPDH), phosphofructokinase, aldolase, hemoglobin, hemichromes, and the protein tyrosine kinase (p72syk).

anion exchange protein; The Anion Exchanger (AE) Family (TC 2.A.31)Characterized protein members of the AE family are found only in animals.They preferentially catalyze anion exchange (antiport) reactions, typically acting as HCO3-:Cl- antiporters, but also transporting a range of other inorganic and organic anions. Additionally, renal Na+:HCO3- cotransporters have been found to be members of the AE family. They catalyze the reabsorption of HCO3- in the renal proximal tubule.

Band 3 cytoplasmic domain; This family contains the cytoplasmic domain of the Band 3 anion exchange proteins that exchange Cl-/HCO3-. Band 3 constitutes the most abundant polypeptide in the red blood cell membrane, comprising 25% of the total membrane protein. The cytoplasmic domain of band 3 functions primarily as an anchoring site for other membrane-associated proteins. Included among the protein ligands of cdb3 are ankyrin, protein 4.2, protein 4.1, glyceraldehyde-3-phosphate dehydrogenase (GAPDH), phosphofructokinase, aldolase, hemoglobin, hemichromes, and the protein tyrosine kinase (p72syk).
