Comments
  • FUNCTION: Spectrin is the major constituent of the cytoskeletal network underlying the erythrocyte plasma membrane. It associates with band 4.1 and actin to form the cytoskeletal superstructure of the erythrocyte plasma membrane.
  • SUBUNIT: Composed of nonhomologous chains, alpha and beta, which aggregate side-to-side in an antiparallel fashion to form dimers, tetramers, and higher polymers.
  • INTERACTION:
    Q8IZP0:ABI1; NbExp=1; IntAct=EBI-375617, EBI-375446;
    P11277:SPTB; NbExp=1; IntAct=EBI-375617, EBI-514908;
    Q01082:SPTBN1; NbExp=2; IntAct=EBI-375617, EBI-351561;
  • SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton. Cytoplasm, cell cortex.
  • DISEASE: Defects in SPTA1 are the cause of elliptocytosis type 2 (EL2) [MIM:182860]. EL2 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 SPTA1 are a cause of hereditary pyropoikilocytosis (HPP) [MIM:266140]. HPP is an autosomal recessive disorder characterized by hemolytic anemia, microspherocytosis, poikilocytosis, and an unusual thermal sensitivity of red cells.
  • DISEASE: Defects in SPTA1 are the cause of spherocytosis type III (SPH3) [MIM:270970]. SPH3 is a disorder characterized by severe hemolytic anemia. Inheritance is autosomal recessive.
  • MISCELLANEOUS: This complex is anchored to the cytoplasmic face of the plasma membrane via another protein, ankyrin, which binds to beta-spectrin and mediates the binding of the whole complex to a transmembrane protein band 3. The interaction of erythrocyte spectrin with other proteins through specific binding domains lead to the formation of an extensive subplasmalemmal meshwork which is thought to be responsible for the maintenance of the biconcave shape of human erythrocytes, for the regulation of plasma membrane components and for the maintenance of the lipid asymmetry of the plasma membrane.
  • SIMILARITY: Belongs to the spectrin family.
  • SIMILARITY: Contains 3 EF-hand domains.
  • SIMILARITY: Contains 1 SH3 domain.
  • SIMILARITY: Contains 22 spectrin repeats.
