Comments
  • FUNCTION: Band 3 is the major integral glycoprotein of the erythrocyte membrane. Band 3 has two functional domains. Its integral domain mediates a 1:1 exchange of inorganic anions across the membrane, whereas its cytoplasmic domain provides binding sites for cytoskeletal proteins, glycolytic enzymes, and hemoglobin.
  • SUBUNIT: A dimer in solution, it spans the membrane asymmetrically and appears to be tetrameric.
  • SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein.
  • TISSUE SPECIFICITY: Erythrocytes.
  • PTM: Phosphorylated on Tyr-8 and Tyr-21 most likely by SYK. PP1-resistant phosphorylation that precedes Tyr-359 and Tyr-904 phosphorylation.
  • PTM: Phosphorylated on Tyr-359 and Tyr-904 most likely by LYN. PP1-inhibited phosphorylation that follows Tyr-8 and Tyr-21 phosphorylation.
  • POLYMORPHISM: SLC4A1 is responsible for the Diego blood group system. The molecular basis of the Di(a)=Di1/Di(b)/Di2 blood group antigens is a single variation in position 854; Leu-854 corresponds to Di(a) and Pro-854 to Di(b). The molecular basis of the Wr(a)=Di3/Wr(b)/Di4 blood group antigens is a single variation in position 658; Lys-658 corresponds to Wr(a) and Glu-658 to Wr(b). The blood group antigens Wd(a)=Di5 (Waldner-type) has Met-557; Rb(a)=Di6 has Leu-548 and WARR=Di7 has Ile-552.
  • POLYMORPHISM: SLC4A1 is responsible for the Swann blood group system (SW) [MIM:601550]. Sw(a+) has a Gln or a Trp at position 646 and Sw(a-) has an Arg.
  • POLYMORPHISM: SLC4A1 is responsible for the Froese blood group system (FR) [MIM:601551]. FR(a+) has a Lys at position 480 and FR(a-) has a Glu.
  • DISEASE: Defects in SLC4A1 are the cause of elliptocytosis type 4 (EL4) [MIM:109270]. EL4 is a Rhesus-unlinked form of hereditary elliptocytosis, a genetically heterogeneous, autosomal dominant hematologic disorder. It is characterized by variable hemolytic anemia and elliptical or oval red cell shape.
  • DISEASE: Defects in SLC4A1 are a cause of hereditary spherocytosis (HS) [MIM:109270]. HS is a hematologic disorder leading to chronic hemolytic anemia and characterized by numerous abnormally shaped erythrocytes which are generally spheroidal.
  • DISEASE: Defects in SLC4A1 are the cause of autosomal dominant distal renal tubular acidosis (dRTA) [MIM:179800]. This disease is characterized by reduced ability to acidify urine, variable hyperchloremic hypokalemic metabolic acidosis, nephrocalcinosis, and nephrolithiasis.
  • DISEASE: Defects in SLC4A1 are the cause of autosomal recessive distal renal tubular acidosis (dRTA) [MIM:611590].
  • MISCELLANEOUS: Phenyl isothiocyanate inhibits anion transport in vitro.
  • SIMILARITY: Belongs to the anion exchanger (TC 2.A.31) family [view classification].
