Summary
The EBVCS-5 antibody is specific for human CD23, also known as the low affinity IgE receptor (FceRII), a 45 kDa type II transmembrane protein and member of the immunoglobulin superfamily. It is expressed on most B cells and is upregulated upon activation. It is also present on mantle zone B cells, eosinophils, monocytes and a subset of T cells and platelets. CD23 plays a role in B cell development and differentiation, and also functions to regulate IgE production. Soluble secreted forms of CD23 have been reported to bind IgE, stimulate release of pro-inflammatory cytokines from monocytes, and play a role in B cell differentiation.

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]
