Immunoglobulin G Receptor (FcγR)

Target
FcγR
Molecular classification
Receptor, Cell surface receptor, Immunoglobulin receptor
01

Overview

Immunoglobulin G receptors are essential mediators between antibodies produced during adaptive immunity and cellular effectors that execute pathogen clearance or modulate inflammation. Their function depends on precise structural features—including glycan recognition—and their balanced signaling is vital for health versus disease states such as autoimmunity or infection susceptibility.
