Isolation and characterization of cardiac amyloid in familial amyloid polyneuropathy type IV (Finnish): relation of the amyloid protein to variant gelsolin.

Abstract excerpt

Amyloid subunit protein was isolated from familial amyloid polyneuropathy type IV (Finnish type) cardiac tissue and purified to homogeneity. N-terminal amino acid sequence analysis shows that the amyloid protein is a fragment of the inner region of human gelsolin. When compared with the predicted sequence of human plasma gelsolin, the amyloid protein contains an asparagine-for-aspartic acid substitution at...
