Product Overview:
Recombinant Cynomolgus Monkey CD200 (Gln56-Gly257) fused with Fc region of Human IgG1 at C-terminal was expressed in CHO.
Description:
CD200, also known as OX-2, is a 45 kDa transmembrane immunoregulatory protein that belongs to the immunoglobulin superfamily. Mature cynomolgus CD200 consists of a 202 aa extracellular domain (ECD) with one Ig-like V-type domain and one Ig-like C2-type domain, a 27 aa transmembrane segment, and a 19 aa cytoplasmic domain. Within the ECD, cynomolgus CD200 shares 95%, 78%, and 78% aa sequence identity with human, mouse, and rat CD200, respectively. CD200 is widely but not ubiquitously expressed. Its receptor (CD200 R1) is restricted primarily to mast cells, basophils, macrophages, and dendritic cells, which suggests myeloid cell regulation as the major function of CD200. CD200 knockout mice are characterized by increased macrophage number and activation and are predisposed to autoimmune disorders. CD200 and CD200 R associate via their respective N-terminal Ig-like domains. In myeloid cells, CD200 R initiates inhibitory signals following receptor-ligand contact. In T cells, however, CD200 functions as a costimulatory molecule independent of the CD28 pathway. Several additional CD200 R-like molecules have been identified in human and mouse, but their capacity to interact with CD200 is controversial. Several viruses encode CD200 homologs which are expressed on infected cells during the lytic phase. Like CD200 itself, viral CD200 homologs also suppress myeloid cell activity, enabling increased viral propagation.
