Summaries for SPTA1 Gene

Entrez Gene Summary for SPTA1 Gene

  • Spectrin is an actin crosslinking and molecular scaffold protein that links the plasma membrane to the actin cytoskeleton, and functions in the determination of cell shape, arrangement of transmembrane proteins, and organization of organelles. It is a tetramer made up of alpha-beta dimers linked in a head-to-head arrangement. This gene is one member of a family of alpha-spectrin genes. The encoded protein is primarily composed of 22 spectrin repeats which are involved in dimer formation. It forms weaker tetramer interactions than non-erythrocytic alpha spectrin, which may increase the plasma membrane elasticity and deformability of red blood cells. Mutations in this gene result in a variety of hereditary red blood cell disorders, including elliptocytosis type 2, pyropoikilocytosis, and spherocytic hemolytic anemia.

GeneCards Summary for SPTA1 Gene

SPTA1 (Spectrin Alpha, Erythrocytic 1) is a Protein Coding gene. Diseases associated with SPTA1 include elliptocytosis-2 and pyropoikilocytosis. Among its related pathways are Sertoli-Sertoli Cell Junction Dynamics and Signaling by GPCR. GO annotations related to this gene include calcium ion binding and actin filament binding. An important paralog of this gene is SYNE2.

UniProtKB/Swiss-Prot for SPTA1 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.

    Size:
    2419 amino acids
    Molecular mass:
    280014 Da
    Quaternary structure:
    • Composed of non-homologous chains, alpha and beta, which aggregate side-to-side in an antiparallel fashion to form dimers, tetramers, and higher polymers. Interacts with FASLG.
    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.
