Protein safeguards against cataracts

The refractive power of the human eye lens relies on a densely packed mixture of proteins. Special protective proteins ensure that these proteins do not clump together as time passes. When this protective mechanism fails, the ocular lens becomes clouded -- the patient develops a cataract. Scientists have now resolved the activation mechanism of one of these protective proteins, laying the foundation for the development of new therapeutic alternatives.http://feeds.sciencedaily.com/~r/sciencedaily/~3/8...
