Product Overview
Recombinant protein of human Fc fragment of IgE, low affinity II, receptor for (CD23) (FCER2), transcript variant 1, residues 48-321aa, with C-terminal DDK tag, expressed in sf9 cells.
Description
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]
