MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The immunoglobulin epsilon receptor (IgE receptor) is the initiator of the allergic response. When two or more high-affinity IgE receptors are brought together by allergen-bound IgE molecules, mediators such as histamine that are responsible for allergy symptoms are released. This receptor is comprised of an alpha subunit, a beta subunit, and two gamma subunits. The protein encoded by this gene represents the alpha subunit. [provided by RefSeq, Aug 2011]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit abnormal mast cell physiology and altered susceptibility to type I hypersensitivity reaction. Mice homozygous for another knock-out allele display altered development of allergic airway inflammation and airway hyperresponsiveness. [provided by MGI curators]
