Asparagine 53-56 gelsolin Homo sapiens 72-80 10767822-1 2000 BACKGROUND: Familial amyloidosis of the Finnish type (FAF, Finnish hereditary amyloidosis) is caused by a 654G-A mutation in the gelsolin gene on chromosome 9 resulting in the expression of mutant Asn-187 gelsolin which is abnormally proteolytically processed generating amyloidogenic fragments that polymerize into amyloid fibrils. Asparagine 197-200 gelsolin Homo sapiens 129-137 10767822-1 2000 BACKGROUND: Familial amyloidosis of the Finnish type (FAF, Finnish hereditary amyloidosis) is caused by a 654G-A mutation in the gelsolin gene on chromosome 9 resulting in the expression of mutant Asn-187 gelsolin which is abnormally proteolytically processed generating amyloidogenic fragments that polymerize into amyloid fibrils. Asparagine 197-200 gelsolin Homo sapiens 205-213 10322122-2 1999 The Asp 187-->Asn (D187N) Asp 187-->Tyr (D187Y) gelsolin mutations facilitate two proteolytic cuts in the parent protein generating a 71-residue fragment that forms amyloid fibrils in humans, putatively causing Finnish type familial amyloidosis (FAF). Asparagine 17-20 gelsolin Homo sapiens 54-62 14640038-10 2003 In homozygous FAF(Asn-187) the 65-kDa fragment containing the amyloid forming region and the 55-kDa fragment, devoid of that region, was the major gelsolin species in the plasma. Asparagine 18-21 gelsolin Homo sapiens 147-155 9354764-2 1997 Herein we show that patients with the Asn-187 gelsolin mutation have, in addition to full-sized gelsolin, a series of lower-Mr C-terminal fragments of gelsolin (Mr of 70,000-45,000) in the circulation, and that a 50 to 55-kd fragment of gelsolin is excreted in the urine. Asparagine 38-41 gelsolin Homo sapiens 46-54 9354764-2 1997 Herein we show that patients with the Asn-187 gelsolin mutation have, in addition to full-sized gelsolin, a series of lower-Mr C-terminal fragments of gelsolin (Mr of 70,000-45,000) in the circulation, and that a 50 to 55-kd fragment of gelsolin is excreted in the urine. Asparagine 38-41 gelsolin Homo sapiens 96-104 9354764-2 1997 Herein we show that patients with the Asn-187 gelsolin mutation have, in addition to full-sized gelsolin, a series of lower-Mr C-terminal fragments of gelsolin (Mr of 70,000-45,000) in the circulation, and that a 50 to 55-kd fragment of gelsolin is excreted in the urine. Asparagine 38-41 gelsolin Homo sapiens 96-104 9354764-2 1997 Herein we show that patients with the Asn-187 gelsolin mutation have, in addition to full-sized gelsolin, a series of lower-Mr C-terminal fragments of gelsolin (Mr of 70,000-45,000) in the circulation, and that a 50 to 55-kd fragment of gelsolin is excreted in the urine. Asparagine 38-41 gelsolin Homo sapiens 96-104 9354764-4 1997 In patients heterozygous for the Asn-187 mutation--the usual form of the expression of the dominant disease--normal-sized gelsolin is the major circulating form; the 65- and 55-kd fragments represent minor components. Asparagine 33-36 gelsolin Homo sapiens 122-130 8176895-6 1994 RESULTS: Ultrastructurally, amyloid-like fibrils were formed from the mutant Asn-187 and Tyr-187 gelsolin peptides corresponding to the naturally occurring missense mutations found in familial gelsolin amyloidosis syndromes, as well as from a gelsolin peptide having a Val-187 substitution. Asparagine 77-80 gelsolin Homo sapiens 193-201 8176895-10 1994 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. Asparagine 296-299 gelsolin Homo sapiens 57-65 8176895-10 1994 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. Asparagine 452-455 gelsolin Homo sapiens 57-65 1849145-7 1991 When compared with the predicted primary structure of human gelsolin a single amino acid substitution is present in amyloid: at position 15 of the amyloid proteins an asparagine is found instead of an aspartic acid residue at the corresponding position (187) in gelsolin. Asparagine 167-177 gelsolin Homo sapiens 60-68 7881424-2 1994 All the analyzed patients are found to carry a nucleotide substitution of A or T for G654 in their gelsolin gene, which at the protein level results in the conversion of the 187 amino acid residue, aspartic acid, to asparagine or tyrosine, respectively. Asparagine 216-226 gelsolin Homo sapiens 99-107 8383491-2 1993 The mutation leads to the expression of mutant Asn-187 gelsolin and the accumulation of amyloid in tissues. Asparagine 47-50 gelsolin Homo sapiens 55-63 1338910-0 1992 Gelsolin-derived familial amyloidosis caused by asparagine or tyrosine substitution for aspartic acid at residue 187. Asparagine 48-58 gelsolin Homo sapiens 0-8 1338910-7 1992 We conclude that substitution of the uncharged Asn or Tyr for the acidic Asp at residue 187 creates a conformation that may be preferentially amyloidogenic for GSN. Asparagine 47-50 gelsolin Homo sapiens 160-163 2176481-0 1990 Gelsolin variant (Asn-187) in familial amyloidosis, Finnish type. Asparagine 18-21 gelsolin Homo sapiens 0-8 2176481-7 1990 We designate this variant of gelsolin-associated amyloidosis "Agel Asn-187". Asparagine 67-70 gelsolin Homo sapiens 29-37
