Monoclonal IgM rheumatoid factors bind IgG at a discontinuous epitope comprised of amino acid loops from heavy-chain constant-region domains 2 and 3.

A combination of site-directed mutagenesis and exon exchange has been used to further define the structure on IgG recognized by monoclonal IgM rheumatoid factors (RFs) from patients with Waldenstrom macroglobulinemia. Most of these RFs bound IgG1, -2, and -4 but not IgG3. For these RFs, His-435 is a...
