Frontiers Interactions of IgG1 CH2 and CH3 Domains with FcRn

WebThe FcRn is an intracellular receptor localized in the acidic compartments of endosomes ( 6 ). By fluid-phase endocytosis, circulating IgGs enter endosomes, the first step of the proteolytic degradation pathway. However, at the low pH of the endosome (pH 6.0), IgGs form a complex with FcRn and are then recycled to the cell surface. WebThe neonatal Fc receptor (FcRn) promotes antibody recycling through rescue from normal lysosomal degradation. The binding interaction is pH-dependent with high affinity at low …
