Chain A   (FCERA_HUMAN | P12319)
molecular function
    GO:0019863    IgE binding    Interacting selectively and non-covalently with an immunoglobulin of the IgE isotype.
    GO:0019767    IgE receptor activity    Combining with an immunoglobulin of the IgE isotype via the Fc region, and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity.
biological process
    GO:0038095    Fc-epsilon receptor signaling pathway    A series of molecular signals initiated by the binding of the Fc portion of immunoglobulin E (IgE) to an Fc-epsilon receptor on the surface of a signal-receiving cell, and ending with regulation of a downstream cellular process, e.g. transcription. The Fc portion of an immunoglobulin is its C-terminal constant region.
    GO:0007257    activation of JUN kinase activity    The initiation of the activity of the inactive enzyme JUN kinase (JNK).
    GO:0000187    activation of MAPK activity    The initiation of the activity of the inactive enzyme MAP kinase (MAPK).
    GO:0007166    cell surface receptor signaling pathway    A series of molecular signals initiated by activation of a receptor on the surface of a cell. The pathway begins with binding of an extracellular ligand to a cell surface receptor, or for receptors that signal in the absence of a ligand, by ligand-withdrawal or the activity of a constitutively active receptor. The pathway ends with regulation of a downstream cellular process, e.g. transcription.
    GO:0019370    leukotriene biosynthetic process    The chemical reactions and pathways resulting in the formation of leukotriene, a pharmacologically active substance derived from a polyunsaturated fatty acid, such as arachidonic acid.
    GO:0050850    positive regulation of calcium-mediated signaling    Any process that activates or increases the frequency, rate or extent of calcium-mediated signaling.
    GO:0045425    positive regulation of granulocyte macrophage colony-stimulating factor biosynthetic process    Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of granulocyte macrophage colony-stimulating factor.
    GO:0045401    positive regulation of interleukin-3 biosynthetic process    Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of interleukin-3.
    GO:0043306    positive regulation of mast cell degranulation    Any process that activates or increases the frequency, rate or extent of mast cell degranulation.
    GO:0050731    positive regulation of peptidyl-tyrosine phosphorylation    Any process that activates or increases the frequency, rate or extent of the phosphorylation of peptidyl-tyrosine.
    GO:0001812    positive regulation of type I hypersensitivity    Any process that activates or increases the frequency, rate or extent of type I hypersensitivity, a type of inflammatory response.
    GO:0001820    serotonin secretion    The regulated release of serotonin by a cell. Serotonin (5-hydroxytryptamine, or 5-HT) is a monoamine synthesised in serotonergic neurons in the central nervous system, enterochromaffin cells in the gastrointestinal tract and some immune system cells.
    GO:0007165    signal transduction    The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.
cellular component
    GO:0009986    cell surface    The external part of the cell wall and/or plasma membrane.
    GO:0009897    external side of plasma membrane    The leaflet of the plasma membrane that faces away from the cytoplasm and any proteins embedded or anchored in it or attached to its surface.
    GO:0016021    integral component of membrane    The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
    GO:0005887    integral component of plasma membrane    The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
    GO:0005622    intracellular    The living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0005886    plasma membrane    The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
