High-affinity receptor for immunoglobulin epsilon/IgE. Mediates IgE effector functions in myeloid cells. Upon IgE binding and antigen/allergen cross-linking initiates signaling pathways that lead to myeloid cell activation and differentiation.

Biological Context

Subcellular Location: Cell membrane (Single-pass type I membrane protein)
Tissue Specificity: Expressed in bone marrow mast cells, as well as in the pineal gland at night

Protein Biology

Function

High-affinity receptor for immunoglobulin epsilon/IgE. Mediates IgE effector functions in myeloid cells. Upon IgE binding and antigen/allergen cross-linking initiates signaling pathways that lead to myeloid cell activation and differentiation. On mast cells, basophils and eosinophils stimulates the secretion of vasoactive amines, lipid mediators and cytokines that contribute to inflammatory response, tissue remodeling and cytotoxicity against microbes. Triggers the immediate hypersensitivity response to allergens as a host defense mechanism against helminth parasites, pathogenic bacteria and venom toxicity. When dysregulated, it can elicit harmful life-threatening allergic and anaphylactic reactions

Subcellular Location

Cell membrane (Single-pass type I membrane protein)

Tissue Specificity

Expressed in bone marrow mast cells, as well as in the pineal gland at night

Subunit

Tetramer of an alpha chain, a beta chain, and two disulfide linked gamma chains. Interacts with IGHE (via CH3 region)

Gene: Fcer1a  |  Organism: Mus musculus  |  Synonyms: Fc-epsilon RI-alpha; IgE Fc receptor subunit alpha
