FcRN present in the intestinal epithelium of neonatal mice and rats mediates the selective uptake of immunoglobulin G (IgG) in mothers' milk, thereby helping newborn animals to acquire passive immunity. FcRn (also designated FCGRT, Brambell receptor, FcRn å chain, IgG Gc receptor and neonatal Fc-receptor) is comprised of a heavy chain and ∫-2-Microglobulin. FcRn heavy chain shows approximately 35% amino acid identity to an MHC class I molecule. FcRN localizes in endosomes of vascular endothelial cells and selectively recycles IgG to the cell surface, thus protecting IgG from lysosomal catabolism. This protection mechanism is a major constituent for ensuring IgG are the longest lived of all plasma proteins.

靶标
基因名
FCGRT
蛋白名
IgG receptor FcRn large subunit p51
亚基
FcRn complex consist of two subunits: p51, and p14 which is equivalent to beta-2-microglobulin. It forms an MHC class I-like heterodimer (By similarity).
亚细胞定位
Cell membrane.
相似性
Belongs to the immunoglobulin superfamily. Contains 1 Ig-like C1-type (immunoglobulin-like) domain.
功能
Binds to the Fc region of monomeric immunoglobulins gamma. Mediates the uptake of IgG from milk. Possible role in transfer of immunoglobulin G from mother to fetus.
