title: Amino acid sequence of band-3 protein from rainbow trout erythrocytes derived from cDNA.
abstract: In this report we present the first complete band-3 cDNA sequence of a poikilothermic lower vertebrate. The primary structure of the anion-exchange protein band 3 (AE1) from rainbow trout erythrocytes was determined by nucleotide sequencing of cDNA clones. The overlapping clones have a total length of 3827 bp with a 5'-terminal untranslated region of 150 bp, a 2754 bp open reading frame and a 3'-untranslated region of 924 bp. Band-3 protein from trout erythrocytes consists of 918 amino acid residues with a calculated molecular mass of 101 827 Da. Comparison of its amino acid sequence revealed a 60-65% identity within the transmembrane spanning sequence of band-3 proteins published so far. An additional insertion of 24 amino acid residues within the membrane-associated domain of trout band-3 protein was identified, which until now was thought to be a general feature only of mammalian band-3-related proteins.
