WebLens cells contain large amounts of crystallins, which are not found in muscle cells. Why do some proteins appear in one type of cell but not in another? During Differentiation, certain genes are activated to produce proteins that enable specific functions. WebJun 13, 2011 · Human gamma D crystallin (γD-crys) is the third most abundant γ-crystallin in the lens and a significant component of the age-onset cataract. It is primarily located in the central lens nucleus, the oldest region of the body, and is therefore one of the longest-lived proteins in the human body. WebThe camera eye lens of vertebrates is a classic example of the re-engineering of existing protein components to fashion a new device. The bulk of the lens is formed from proteins belonging to two superfamilies, the α-crystallins and the βγ-crystallins.Tracing their ancestry may throw light on the origin of the optics of the lens. hi def converter box
