| UniProt functional annotation for P12319 | |||
| UniProt code: P12319. |
| Organism: | Homo sapiens (Human). | |
| Taxonomy: | Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo. | |
| 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. | |
| Subunit: | Tetramer of an alpha chain, a beta chain, and two disulfide linked gamma chains. | |
| Subcellular location: | Cell membrane; Single-pass type I membrane protein. | |
