Application
α-Crystallin is a lens protein that contains two homologous subunits: αA- and αB-crystallins. α-Crystallin displays chaperone-like activity and plays an important role in maintaining lens transparency. It has been noted that in diabetic conditions of rats there is a decline in the chaperone activity of α-Crystallin. Research has shown that a dietary antioxidant, curcumin, can prevent this loss of chaperone activity.
Biochem/physiol Actions
α-Crystallin is a small heat-shock protein that has chaperone-like activity, preventing protein aggregation in vitro. Point mutations in α-crystallin genes are believed to be responsible for hereditary cataract development.

This research aims to probe the interaction of α-crystallin with a model of human, porcine, and mouse lens-lipid membranes. Cholesterol/model of human lens-lipid (Chol/MHLL), cholesterol/model of porcine lens-lipid (Chol/MPLL), and cholesterol/model of mouse lens-lipid (Chol/MMLL) membranes with 0-60 mol% Chol were

The concentration of α-crystallin decreases in the eye lens cytoplasm, with a corresponding increase in membrane-bound α-crystallin during cataract formation. The eye lens's fiber cell plasma membrane consists of extremely high cholesterol (Chol) content, forming cholesterol bilayer domains (CBDs) within

It is well-studied that the significant factor in cataract formation is the association of α-crystallin, a major eye lens protein, with the fiber cell plasma membrane of the eye lens. The fiber cell plasma membrane of the eye lens consists

Purpose/Aim: The amount of membrane-bound α-crystallin increases significantly with age and cataract formation, accompanied by a corresponding decline in the level of α-crystallin in the lens cytoplasm. The purpose of this research is to evaluate the binding affinity of α-crystallin
