SPTBN1

Spectrin, beta, non-erythrocytic 1

 

  • Alias                                 (According to NCBI)

 
  • SPTB2
  • Spectrin, beta, nonerythrocytic-1 (beta-fodrin)
  • spectrin, beta, non-erythrocytic 1
  • Spectrin beta chain, brain 1 (Spectrin, non-erythroid beta chain 1) (Beta-II spectrin) (Fodrin
    beta chain).

  • Spectrin is a tetrameric cytoskeletal protein essential for determination of cell shape, resilience of membranes to mechanical stress, positioning of transmembrane proteins, and organization of organelles and molecular traffic. Alpha- and beta-spectrin subunits form antiparallel dimers that self associate to give the spectrin tetramer. Beta subunits, such as SPTBN1, contain most of the spectrin binding activity (Hayes et al., 2000).
