WebThe action of alpha crystallin as a molecular chaperone may inhibit abnormal interactions that favor phase separation and light scattering ( Horwitz, 1992; Muchowski et al., 1997). The effects of cellular metabolism, either direct or indirect, on cytoplasmic phase separation is an important area of investigation. WebDec 1, 2012 · Crystallins are the abundant, long-lived proteins of the eye lens. The major human crystallins belong to two different superfamilies: the small heat-shock proteins (α-crystallins) and the βγ-crystallins. During evolution, other proteins have sometimes been recruited as crystallins to modify the properties of the lens. canara bank salem town branch ifsc code

Webα-Crystallins are small heat-shock proteins that act as holdase chaperones. 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. WebJul 10, 2024 · The crystalline lens is a small but powerful structure that is vital to your ability to see clearly.
