cDNA sequence and deduced amino acid sequence of C-terminus human -spectrin. (A) Published sequence. (B) Corrected sequence. The addition of G (underlined base) cause a change in reading frame resulting in a molecule 11 amino acids shorter (2418 residues instead of 2429) and different in amino acid sequence 2399-2418. (C) Comparison of C-terminus amino acid corrected sequence of human -spectrin (underlined sequence), human -fodrin, chicken -fodrin, drosophila -spectrin.
