Epitopes on proteinase-3 recognized by antibodies from patients with Wegener's granulomatosis.


The 228 amino acid primary sequence of proteinase-3 (PR3) was studied for antigenic epitopes, which react with IgG Ab in sera of patients with Wegener's granulomatosis, by synthesizing overlapping 7 mers of PR3 linear sequence on pins. Main regions of linear sequence reactivity included GHEAQPH (at residues 4-10), QPHSRPY (8-14), TQEPTQQ (65-71), ATVQLPQ… (More)
