Webα-Crystallin, a major component of the eye lens cytoplasm, is a large multimer formed from two members of the small heat shock protein (sHsp) family. Inherited crystallin mutations are a common cause of childhood cataract, whereas miscellaneous changes to the long-lived crystallins cause age-related cataract, the most common cause of blindness worldwide. WebThe name "crystallin" is rather ironic. 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 …
