Biochem/physiol Actions
γ-Crystallin is a natural substrate for the small heat-shock protein and molecular chaperone α-crystallin. γ-Crystallin competes with Cu2+ and Zn2+ for binding to α-crystallin, reducing the latter′s chaperone capacity.
Preparation Note
Further purified from the BO-5 fraction of Chiou, S., et al., to remove βs-crystallin.
