WebCrystallins 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 …
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.

In humans, αA-crystallin is expressed only in the eye lens, while αB-crystallin is found in many tissues. α-Crystallins have a central domain flanked by flexible extensions and form dynamic, heterogeneous oligomers.
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, … WebAlpha-crystallin Alpha A and alpha B-crystallins are a major protein component of the mammalian eye lens. Being a member of the small heat-shock protein family they possess chaperone-like function. The alpha-crystallins and especially alpha B is also found outside the lens having an extensive tissue distribution. Al …
WebCrystallins are the main constituent of the lens and are separated into three types in vertebrates: α, β and γ-crystallins [ 6, 7 ]. α-Crystallin is the predominant and biggest type of crystallins, with a molecular weight around 800 kDa [ 6 ].
WebMammalian lens crystallins are divided into alpha, beta, and gamma families. Alpha crystallins are composed of two gene products: alpha-A and alpha-B, for acidic and basic, respectively. Alpha crystallins can be induced by heat shock and are members of the small heat shock protein (HSP20) family. They act as molecular chaperones although they do … high pressure cold water jet machineWebDec 1, 2012 · Crystallins are the abundant, long-lived proteins of the eye lens.

The latter class constitutes the major proteins of vertebrate eye lens and maintains the transparency and refractive index of the lens. Since lens central fiber cells lose their nuclei during development, these crystallins are made and then retained throughout life, making them extremely stable proteins.
