Protease-activated alpha-2-macroglobulin can inhibit amyloid formation via two distinct mechanisms
Abstract α2-Macroglobulin (α2M) is an extracellular chaperone that inhibits amorphous and fibrillar protein aggregation. The reaction of α2M with proteases results in an ‘activated’ conformation, where the proteases become covalently-linked within...
