Role of the N and C-terminal strands of beta 2-microglobulin in amyloid formation at neutral pH.

Abstract excerpt

Beta 2-microglobulin (beta(2)m) is known to form amyloid fibrils de novo in vitro under acidic conditions (below pH 4.8). Fibril formation at neutral pH, however, has only been observed by deletion of the N-terminal six residues; by the addition of pre-assembled seeds; or in the presence of Cu(2+). Based on these observations, and other structural data, models for fibril formation of beta(2)m have been proposed...
