background | The neonatal Fc receptor (FCRN) is an approximately 45 kDa transmembrane glycoprotein with structural homology to MHC class I proteins. It is widely expressed in endothelial and epithelial cells and plays an important role in IgG homeostasis and antigen presentation by dendritic cells.FCGRT & B2M heterodimer protein (FcRn complex) consist of two subunits: p51, and p14, and forms an MHC class I-like heterodimer. |
molecular weight | The protein has a predicted MW of 47.1 kDa. Due to glycosylation, the protein migrates to 50-70 kDa based on Tris-Bis PAGE result. |

Function Cell surface receptor that transfers passive humoral immunity from the mother to the newborn. Binds to the Fc region of monomeric immunoglobulin gamma and mediates its selective uptake from milk (PubMed:10933786, PubMed:7964511). IgG in the milk is bound at the apical surface of the intestinal epithelium. The resultant FcRn-IgG complexes are transcytosed across the intestinal epithelium and IgG is released from FcRn into blood or tissue fluids. Throughout life, contributes to effective humoral immunity by recycling IgG and extending its half-life in the circulation. Mechanistically, monomeric IgG binding to FcRn in acidic endosomes of endothelial and hematopoietic cells recycles IgG to the cell surface where it is released into the circulation (PubMed:10998088). In addition of IgG, regulates homeostasis of the other most abundant circulating protein albumin/ALB (PubMed:24469444, PubMed:28330995). {ECO:0000250|UniProtKB:P13599, ECO:0000269|PubMed:10933786, ECO:0000269|PubMed:10998088, ECO:0000269|PubMed:24469444, ECO:0000269|PubMed:28330995, ECO:0000269|PubMed:7964511}.; (Microbial infection) Acts as an uncoating receptor for a panel of echoviruses including Echovirus 5, 6, 7, 9, 11, 13, 25 and 29. {ECO:0000269|PubMed:30808762, ECO:0000269|PubMed:31104841}. |

Structure FcRn complex consists of two subunits: p51, and p14 which is equivalent to beta-2-microglobulin. It forms an MHC class I-like heterodimer (By similarity). Interacts with albumin/ALB; this interaction regulates ALB homeostasis (PubMed:24469444, PubMed:28330995). {ECO:0000250|UniProtKB:P13599, ECO:0000269|PubMed:24469444, ECO:0000269|PubMed:28330995}.; (Microbial infection) Interacts with Echovirus 6, Echovirus 11 and Echovirus 30 capsid protein VP1. {ECO:0000269|PubMed:30808762, ECO:0000269|PubMed:31104841}. |
