Human Gene FCER2 (ENST00000346664.9) from GENCODE V44
  Description: 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). (from UniProt P06734)
RefSeq Summary (NM_002002): 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].

DESCRIPTION: RecName: Full=Low affinity immunoglobulin epsilon Fc receptor; AltName: Full=BLAST-2; AltName: Full=C-type lectin domain family 4 member J; AltName: Full=Fc-epsilon-RII; AltName: Full=Immunoglobulin E-binding factor; AltName: Full=Lymphocyte IgE receptor; AltName: CD_antigen=CD23; Contains: RecName: Full=Low affinity immunoglobulin epsilon Fc receptor membrane-bound form; Contains: RecName: Full=Low affinity immunoglobulin epsilon Fc receptor soluble form;
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).
SUBCELLULAR LOCATION: Cell membrane; Single-pass type II membrane protein. Secreted. Note=Also exists as a soluble excreted form.
PTM: N- and O-glycosylated.
MISCELLANEOUS: There are two kinds of Fc receptors for IgE, which differ in both structure and function: high affinity receptors on basophils and mast cells and low affinity receptors on lymphocytes and monocytes.
SIMILARITY: Contains 1 C-type lectin domain.
SEQUENCE CAUTION: Sequence=AAA52433.1; Type=Erroneous gene model prediction;

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
