Figure 1. Schematic diagram showing the regions and residue numbers forming the NH₂-terminal domain (NTD), core domain (CD), and COOH-terminal extension (CTE) of αA- and αB-crystallins in the current study. The residues spanned by each domain were as follows: αA NTD (residues no.1–63), αA CD (residues no. 64–142), αA CTE (residues no. 143–173), αB NTD (residues no. 1–66), αB CD (residues no. 67–146), and αB CTE (residues no. 147–175).
