1 CONCLUSIONS: We have defined the amyloidogenic region of gelsolin to a 9-residue sequence in the highly conserved repetitive motif B and showed that residue 187 represents a critical site where a substitution of an amino acid with a charged side chain (Asp) with an amino acid with an uncharged (Asn) or hydrophobic side chain (Tyr, Val) creates a conformation that is highly amyloidogenic thus providing an explanation for the amyloidogenicity of the Asn-187 and Tyr-187 gelsolin variants.
