Identification of amino acid residues involved in the interaction of canine IgE with canine and human FcεRIα.

Abstract excerpt

The interaction of immunoglobulin E (IgE) antibodies with the high-affinity receptor (FcεRI) is important in anti-parasitic immunity and plays a central role in allergic responses. It has been shown that the human Cε3 domains comprise the binding sites for FcεRIα and crystal structure determination has shown that amino acids in four sites contribute to the high affinity of the interaction. The role of homologous...
