Web9 mei 2014 · All Ig domains of CHIRs, KIRs, LILRs, the FcRL and the classical FcRs are classed as C2 domains and the Ig domains of the PIGR, IgM, and IgA/IgM receptors are V type domains , . An interesting possibility is that all of these Ig-domain receptors within the FcR locus and the LRC originate from a common ancestor. Web8 sep. 2024 · Three different receptors that interact with the constant domains of IgM have been identified: the polymeric immunoglobulin (Ig) receptor (PIGR), the dual receptor for IgA/IgM (FcαµR) and the IgM receptor (FcµR). All of them are related in structure and located in the same chromosomal region in mammals.
