From: Genomic organization and molecular phylogenies of the beta (β) keratin multigene family in the chicken (Gallus gallus) and zebra finch (Taeniopygia guttata): implications for feather evolution

Figure 1

Amino Acid Alignment of β-keratins showing the 32aa Filament Segment of Feathers: Alignment of the two most diverged feather β-keratins from each chromosome of G. gallus and T. guttata. Annotation of the sequences includes the three letter abbreviation of the species, the chromosome number, type of β-keratin, and the number indicating position in the 5' to 3' direction on each chromosome. The 31 amino acids in the box comprise those described by Fraser and Parry [22] as the 32-residue segment constituting the filament framework of feather β-keratins. Both the G. gallus and T. guttata β-keratins possess a deletion in position 3 of the 32-residue segment.
