Fc gamma receptor IIb (FCGR2B/CD32B) is an inhibitory low-affinity receptor for the Fc region of IgG. It contributes to immune-complex handling and helps regulate B-cell activation and antibody production, providing an important counter-regulatory signal within Fc receptor biology.
FCGR2B/CD32B is widely studied in inhibitory Fc-gamma receptor signalling, immune-complex biology and regulation of B-cell responses.
