AA-amyloidosis. Tissue component-specific association of various protein AA subspecies and evidence of a fourth SAA gene product
Protein AA, the major repetitive protein subunit present in fibrils deposited in AA-amyloidosis, is an N-terminal cleavage product of a 104-amino acid precursor, serum amyloid A (SAA). Protein AA subspecies varying between 45 and 94 amino acids in length have been described. In this study it is shown that the different protein AA subspecies are not evenly distributed in amyloid deposits and that i
