Crystal structure at 2.2 Å resolution of the MHC-related neonatal Fc receptor
Abstract
The three-dimensional structure of the rat neonatal Fc receptor (FcRn) is similar to the structure of molecules of the major histocompatibility complex (MHC). The counterpart of the MHC peptide-binding site is closed in FcRn, making the FcRn groove incapable of binding peptides. A dimer of FcRn heterodimers seen in the crystals may represent a receptor dimer that forms when the Fc portion of a single immunoglobulin binds. An alternative use of the MHC fold for immune recognition is indicated by the FcRn and FcRn/Fc co-crystal structures.
