Summaries for SPTB Gene

Entrez Gene Summary for SPTB Gene

  • This locus encodes a member of the spectrin gene family. Spectrin proteins, along with ankyrin, play a role in cell membrane organization and stability. The protein encoded by this locus functions in stability of erythrocyte membranes, and mutations in this gene have been associated with spherocytosis type 2, hereditary elliptocytosis, and neonatal hemolytic anemia. Alternatively spliced transcript variants have been described. [provided by RefSeq, Nov 2009]

GeneCards Summary for SPTB Gene

SPTB (Spectrin Beta, Erythrocytic) is a Protein Coding gene. Diseases associated with SPTB include Sptb-Related Spherocytosis and Elliptocytosis 3. Among its related pathways are Interleukin-3, 5 and GM-CSF signaling and Signaling by GPCR. GO annotations related to this gene include protein heterodimerization activity and actin filament binding. An important paralog of this gene is SPTBN1.

UniProtKB/Swiss-Prot for SPTB Gene

  • 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.

    • Composed of nonhomologous chains, alpha and beta, which aggregate to form dimers, tetramers, and higher polymers.
    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.
