WebFeb 1, 2007 · Crystallins are the predominant structural proteins in the lens that are evolutionarily related to stress proteins. They were first discovered outside the vertebrate eye lens by Bhat and... WebThe Crystalline Lens. The transparent crystalline lens of the eye is located immediately behind the iris . It is composed of fibers that come from epithelial (hormone-producing) cells. In fact, the cytoplasm of these cells makes up the transparent substance of the lens. The crystalline lens is composed of 4 layers, from the surface to the center:

Crystallins have been perfected by evolution expressly for their ability not to form crystals. The eye lens needs to be a highly concentrated solution, but it needs to avoid small crystals …
WebNov 30, 2015 · They ran a screen of small molecules, looking for ones that could make clumped-up α-crystallins fall apart at lower temperatures. Such molecules could restore overwhelmed or damaged chaperones in the lens. The team tested 2,450 compounds and found 32 that lowered α-crystallins’ melting temperature. Of those 32, 12 were oxysterols.
