GeneID: 2208 Human FCER2

Swiss-port # P06734 Human Low affinity immunoglobulin epsilon Fc receptor

Gene Symbol FCER2
Gene Full Name Fc fragment of IgE, low affinity II, receptor for (CD23)
Background 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 factor. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.[provided by RefSeq, Jul 2011]
Function Low-affinity receptor for immunoglobulin E (IgE) and CR2/CD21. Has essential roles in the regulation of IgE production and in the differentiation of B-cells (it is a B-cell-specific antigen). [UniProt]
