The FcRI complex forms a high-affinity cell-surface receptor for the Fc region of antigen-specific immunoglobulin E (IgE) molecules. FcRI is multimeric and is a member of a family of related antigen/Fc receptors which have conserved structural features and similar roles in initiating intracellular signalling cascades.
Most important Ig in secondary Ab response. Most abundant in serum. IgG1 and IgG3 are cytophilic (Fc regions bind to Fc receptors on other cells) IgG1-3 activate the classical complement cascade. IgG can cross the placenta.
