Lens crystallins: gene recruitment and evolutionary dynamism

Trends Biochem Sci. 1993 Aug;18(8):301-6. doi: 10.1016/0968-0004(93)90041-k.

Abstract

In a novel evolutionary process, enzymes and stress proteins have undergone direct gene recruitment as eye lens crystallins in a number of independent events. This may have allowed a dynamic response to changing visual environment during evolution. In spite of their diversity, many crystallins may share an origin in essential developmental processes such as cell elongation.
