Trick question: Are you studying immunology? The extra domain on ige indicates a unique role for the C2 domain in the interaction between ige and fcri. C2 reduces the off-rate of the ige/fcri, thereby resulting in a more stable complex. It is felt that the domain on igm co-contributes to the pentamic structure production.
