CD23/Fc epsilon RII Protein, a low-affinity receptor for IgE and CR2/CD21, regulates IgE production and B cell differentiation. On B cells, it initiates IgE-dependent antigen uptake and presentation to T cells. On macrophages, IgE binding induces intracellular killing of parasites through the L-Arginine-nitric oxide pathway. CD23/Fc epsilon RII homotrimer interacts with IGHE to regulate IgE homeostasis and with CR2/CD21 for binding. CD23/Fc epsilon RII Protein, Mouse (HEK293, His) is the recombinant mouse-derived CD23/Fc epsilon RII protein, expressed by HEK293 , with N-His labeled tag. The total length of CD23/Fc epsilon RII Protein, Mouse (HEK293, His) is 282 a.a., with molecular weight of 33-43 kDa.

The CD23/Fc epsilon RII protein serves as a low-affinity receptor for immunoglobulin E (IgE) and CR2/CD21, playing crucial roles in the regulation of IgE production and B cell differentiation. On B cells, it initiates IgE-dependent antigen uptake and presentation to T cells, contributing to immune response modulation. In macrophages, CD23, upon binding IgE and cross-linking with antigens, triggers intracellular killing of parasites through the activation of the L-Arginine-nitric oxide pathway. Existing as a homotrimer, CD23 interacts with IGHE, regulating IgE homeostasis through its C-type lectin domain. Additionally, CD23 interacts with CR2/CD21 through its C-terminus, forming a connection via the Sushi domains 1 and 2. These interactions underscore the multifaceted involvement of CD23 in immunological processes, influencing both B cell function and macrophage-mediated responses.
