WebJan 15, 2024 · For both the proteins, the crystal structure of only the truncated proteins (residue number 62–163 for αΑ-crystallin and residue number 68–162 for αB-crystallin) are reported. The above structures include mostly the α-crystallin domain (commonly found in small heat shock proteins) and part of C-terminal region.
Crystallins are separated into two classes: taxon-specific, or enzyme, and ubiquitous. The latter class constitutes the major proteins of vertebrate eye lens and maintains the transparency and refractive index of the lens. Since lens central fiber cells lose their nuclei during development, these crystallins are made and then retained throughout life, making them extremely stable proteins.
