FcRn
The neonatal fragment crystallizable (Fc) receptor is a protein that in humans is encoded by the FCGRT gene. It is an IgG Fc receptor which is similar in structure to the MHC class I molecule and also associates with beta-2-microglobulin. In rodents, FcRn was originally identified as the receptor that transports maternal immunoglobulin G (IgG) from mother to neonatal offspring via mother's milk, leading to its name as the neonatal Fc receptor. In humans, FcRn is present in the placenta where it transports mother's IgG to the growing fetus. FcRn has also been shown to play a role in regulating IgG and serum albumin turnover. Neonatal Fc receptor expression is up-regulated by the proinflammatory cytokine, TNF, and down-regulated by IFN-γ.
