Tissue Specificity | Expressed specifically by polymorphonuclear leukocytes (neutrophils). Also expressed by stimulated eosinophils. |
Post Translational Modifications | Glycosylated. Glycosylation plays an inhibitory role in the interaction with IgG3. The soluble form is produced by a proteolytic cleavage. |
Function | Receptor for the Fc region of immunoglobulins gamma. Low affinity receptor. Binds complexed or aggregated IgG and also monomeric IgG. Contrary to III-A, is not capable to mediate antibody-dependent cytotoxicity and phagocytosis. May serve as a trap for immune complexes in the peripheral circulation which does not activate neutrophils. |
