Human gamma-crystallins are long-lived, unusually stable proteins of the eye lens exhibiting duplicated, double Greek key domains. The lens also contains high concentrations of the small heat shock chaperone alpha-crystallin, which suppresses aggregation of model substrates in vitro. Mature-onset cataract is believed to represent an aggregated state of partially unfolded and covalently damaged crystallins. The alphaB-crystallin oligomers formed long-lived stable complexes with their gammaD-crystallin substrates. These in vitro results provide support for protein unfolding/protein aggregation models for cataract, with alpha-crystallin suppressing aggregation of damaged or unfolded proteins through early adulthood but becoming saturated with advancing age. |

The γ-crystallin proteins are tightly folded in two domains with no free loops. It is possible that the R58H mutation destabilizes the contact between lens-fiber cells, which is critical for the maintenance of lens transparency. Improper folding of CRYGD, the most abundantly expressed γ-crystallin in the lens, could well cause protein aggregation and lens opacification. |
