In anatomy, a crystallin is a water-soluble structural protein found in the lens and the cornea of the eye accounting for the transparency of the structure. It has also been identified in other places such as the heart, and in aggressive breast cancer tumors. Since it has been shown that lens injury may promote … See more The main function of crystallins at least in the lens of the eye is probably to increase the refractive index while not obstructing light. However, this is not their only function. It has become clear that crystallins may … See more Some crystallins are active enzymes, while others lack activity but show homology to other enzymes. The crystallins of different groups of organisms are related to a large number of different proteins, with those from birds and reptiles related to lactate dehydrogenase See more • Crystallins at the U.S. National Library of Medicine Medical Subject Headings (MeSH) • alpha-Crystallins at the U.S. National Library of Medicine Medical Subject Headings (MeSH) • Lens Crystallin Crystal Structures by Christine Slingsby, Birkbeck College See more Crystallins from a vertebrate eye lens are classified into three main types: alpha, beta and gamma crystallins.
