Description : The transparency and high refractive index of the normal eye lens necessary for focusing
visible light on the retina is achieved by a regular arrangement of the lens fiber
cells during growth of the lenticular body and by the high concentration and the supramolecular
organization of the alpha-, beta- (see 123610), and gamma- (see 123660) crystallins,
the major protein components of the vertebrate eye lens. Alpha-crystallin is composed
of 2 primary gene products--alpha-A and alpha-B (123590) (summary by Moormann et al.,
1982).;
