My laboratory studies the biochemical basis of human cataract formation. Several approaches are being used at understanding the function of alpha-crystallin, a major protein of the lens and a member of the small heat shock protein family of molecular chaperones. This protein, composed of two gene products alpha A and alpha B, plays important roles in the lens and other tissues. Mutations in alpha A and alpha B crystallins form the basis of several hereditary cataracts. To understand the function of alpha-crystallin in the lens, and how deterioration of chaperone function results in cataract development., we are using several genetic and biochemical approaches.
