The N-terminal domain of alphaB-crystallin is protected from proteolysis by bound substrate.


Alpha-crystallin, a major structural protein of the lens can also function as a molecular chaperone by binding to unfolding substrate proteins. We have used a combination of limited proteolysis at low temperature, and mass spectrometry to identify the regions of alpha-crystallin directly involved in binding to the structurally compromised substrate, reduced… (More)
