Target

  • Function
    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.
  • Sequence similarities
    Contains 2 Ig-like (immunoglobulin-like) domains.
  • Cellular localization
    Cell membrane.
