| Post Translational Modifications | N- and O-glycosylated. The secreted form sCD23 is produced by ADAM10-mediated ectodomain shedding. |
| 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. On B cells, initiates IgE-dependent antigen uptake and presentation to T cells. On macrophages, upon IgE binding and antigen cross-linking induces intracellular killing of parasites through activation of L-Arginine-nitric oxide pathway. |
