Neonatal Fc Receptor The neonatal Fc receptor (FcRn) was initially identified as an immunoglobulin G (IgG) receptor in the intestinal epithelial cells of neonatal rodents (Simister and Rees, 1985 ) FcRn transports IgG from the maternal milk across the mucosal layer and releases it into blood of neonatal rodents to endow passive immunityThe neonatal fragment crystallizable (Fc) receptor (FcRn) is a multifunctional atypical Fcgamma receptor (FcγR) FcRn was initially identified as responsible for IgG transport from maternal to fetal circulation across the placenta, and later for IgG recyclingNeonatal Fc receptor is similar to these proteins Polymeric immunoglobulin receptor, CC chemokine receptor type 7, Smoothened and more

Neonatal fc receptor antibody
Neonatal fc receptor antibody- IgG and albumin are the most abundant proteins in the circulation and have the longest halflives These properties are due to a unique receptor, the neonatal Fc receptor (FcRn) Although FcRn is named for its function of transferring IgG across the placenta from maternal to fetal circulation, FcRn functions throughout life to maintain IgG and albumin concentrations FcRn protects IgG Neonatal Fcreceptor The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome This score cannot be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein
Abstract The neonatal Fc receptor for IgG (FcRn) has been well characterized in the transfer of passive humoral immunity from a mother to her fetus In addition, throughout life, FcRn protects IgG from degradation, thereby explaining the long halflife of this class of antibody in the serum In recent years, it has become clear that FcRn is expressed in various sites in adults, where its The neonatal Fc receptor for IgG (FcRn) is a heterodimer consisting of an MHCclassIlike heavy chain (shown in turquoise) and a β 2microglobulin (β 2 m) light chain (shown in green), which isCloning and analysis of the gene encoding the human neonatal Fc receptor (PMID ) Mikulska JE Simister NE (European journal of immunogenetics official journal of the British Society for Histocompatibility and Immunogenetics 00) 3 4 22;
