| 1354370 | FCER2 | Fc epsilon receptor II | The protein encoded by this gene is a B-cell specific antigen, and a low-affinity receptor for IgE. It has essential roles in B cell growth and differentiation, and the regulation of IgE production. This protein also exists as a soluble secreted form, then functioning as a potent mitogenic growth fa ctor. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.[provided by RefSeq, Jul 2011] | 19 | 7688776 | 7702131 | Human | 101 | symbol , COSMIC , Human Proteome Map | gene, protein-coding, REVIEWED [RefSeq] |
