Binding of gamma crystallin substrate prevents the binding of copper and zinc ions to the molecular chaperone alpha crystallin

α-crystallin is a small heat shock protein and molecular chaperone. Binding of Cu(2+) and Zn(2+) ions to α-crystallin leads to enhanced chaperone function. Sequestration of Cu(2+) by α-crystallin prevents metal-ion mediated oxidation. Here we show that binding of human γD-crystallin (HGD, a natural...
