Amino acid sequence of the Fc region of a canine immunoglobulin M: interspecies homology for the IgM class
RL Wasserman
and
JD Capra
The amino acid structure for the Fc portion of a canine immunoglobulin mu chain was determined. The sequence was compared with those of two human mu chains, and a high degree of interspecies homology was observed. The preservation of primary structure between species is probably reflective of the unique functions associated with the immunoglobulin M class.
