Gene Information

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.

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

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

Molecular chaperones are essential to maintain proteostasis. While the functions of intracellular molecular chaperones that oversee protein synthesis, folding and aggregation, are established, those specialized to work in the extracellular environment are less understood. Extracellular proteins reside in a considerably

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

A decline in the chaperone-like activity of eye lens alpha-crystallin in diabetic conditions has been reported. In this study, we investigated whether curcumin, a dietary antioxidant, can manipulate the chaperone-like activity of alpha-crystallin in diabetic rat lens. A group of
