      Entrez Gene Number
      Entrez Gene SummaryThe IgE receptor plays a central role in allergic disease, coupling allergen and mast cell to initiate the inflammatory and immediate hypersensitivity responses that are characteristic of disorders such as hay fever and asthma. The allergic response occurs when 2 or more high-affinity IgE receptors are crosslinked via IgE molecules that in turn are bound to an allergen (antigen) molecule. A perturbation occurs that brings about the release of histamine and proteases from the granules in the cytoplasm of the mast cell and leads to the synthesis of prostaglandins and leukotrienes--potent effectors of the hypersensitivity response. The IgE receptor consists of 3 subunits: alpha, beta (MIM 147138), and gamma (MIM 147139); only the alpha subunit is glycosylated.[supplied by OMIM]

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P12319 # Binds to the Fc region of immunoglobulins epsilon. High affinity receptor. Responsible for initiating the allergic response. Binding of allergen to receptor-bound IgE leads to cell activation and the release of mediators (such as histamine) responsible for the manifestations of allergy. The same receptor also induces the secretion of important lymphokines.
      SIZE: 257 amino acids; 29596 Da
      SUBUNIT: Tetramer of an alpha chain, a beta chain, and two disulfide linked gamma chains.
      SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein.
      SIMILARITY: SwissProt: P12319 ## Contains 2 Ig-like (immunoglobulin-like) domains.
