||Primary source abstract: "[Investigators] report the isolation from a placental cDNA library of clones encoding the alpha-chain of an immunoglobulin G (IgG)-Fc receptor (hFcRn) that resembles a class I major histocompatibility complex antigen."
||P.86 right column 3rd paragraph: "The DNA and predicted amino acid sequences of human FcRn are very similar to those of the neonatal rat and mouse intestinal FcRn. Human FcRn α-chain shares 65% predicted amino acid sequences with the rat homologue (primary source)." Primary source abstract: "The DNA and predicted amino acid sequences [of the alpha-chain of an immunoglobulin G (IgG)-Fc receptor (hFcRn) that resembles a class I major histocompatibility complex antigen] are very similar to those of the neonatal rat and mouse intestinal Fc receptors, rFcRn and mFcRn."
