IgE receptors

IgE receptors
membrane receptors for immunoglobulin E (IgE) on mast cells and basophils; the IgE molecules are bound by a site in the Fc region, leaving their antigen-binding sites exposed; binding of a multivalent antigen that cross-links the receptors triggers release of mediators of immediate hypersensitivity.
