FCGRT Antibody (YA4105)

FCGRT Antibody (YA4105) is a mouse-derived and non-conjugated IgG1 antibody, targeting to FCGRT. It can be applicated for FC, ELISA assays, in the background of human.

FCGRT, a crucial cell surface receptor, facilitates the transfer of passive humoral immunity from the mother to the newborn by binding to the Fc region of monomeric immunoglobulin gamma and selectively mediating its uptake from milk. The process involves IgG binding at the apical surface of the intestinal epithelium, forming FcRn-IgG complexes that transcytose across the intestinal epithelium, releasing IgG into blood or tissue fluids. Beyond infancy, FCGRT plays a pivotal role in effective humoral immunity by recycling IgG and prolonging its half-life in the circulation. Mechanistically, the binding of monomeric IgG to FCGRT in acidic endosomes of endothelial and hematopoietic cells facilitates the recycling of IgG to the cell surface, subsequently releasing it into circulation. Additionally, FCGRT regulates the homeostasis of albumin/ALB, the other most abundant circulating protein, further underscoring its essential role in immune and protein homeostasis. In the context of microbial infection, FCGRT acts as an uncoating receptor for various echoviruses, including Echovirus 5, 6, 7, 9, 11, 13, 25, and 29.
