Descripción
CD46, also known as membrane cofactor protein (MCP), is a transmembrane glycoprotein that serves primarily as a regulatory component of the complement system, protecting host cells from complement-mediated damage. CD46 is widely expressed on almost all nucleated cells and plays a key role in immune regulation, ensuring that the complement system, which is responsible for clearing pathogens, does not attack the body’s own cells. CD46 does this by serving as a cofactor for the proteolytic cleavage of C3b and C4b, two crucial components of the complement pathway, which are inactivated by factor I. In addition to its role in the complement system, CD46 is involved in various immune functions, including modulation of T-cell responses, immune tolerance, and viral entry. Several viruses, such as the measles virus and human herpesvirus 6 (HHV-6), use CD46 as a receptor to gain entry into host cells, highlighting its involvement in viral pathogenesis.

CD46 antibody
Acts as a cofactor for complement factor I, a serine protease which protects autologous cells against complement-mediated injury by cleaving C3b and C4b deposited on host tissue. May be involved in the fusion of the spermatozoa with the oocyte during fertilization. Also acts as a costimulatory factor for T-cells which induces the differentiation of CD4+ into T-regulatory 1 cells. T-regulatory 1 cells suppress immune responses by secreting interleukin-10, and therefore are thought to prevent autoimmunity. (Microbial infection) A number of viral and bacterial pathogens seem to bind MCP in order to exploit its immune regulation property and directly induce an immunosuppressive phenotype in T-cells. Acts as a receptor for adenovirus subgroup B2 and Ad3, cultured measles virus and herpesvirus 6(PubMed:10972291, PubMed:12663806, PubMed:12724329, PubMed:12915534, PubMed:14566335, PubMed:15047806, PubMed:15078926, PubMed:15919905, PubMed:16254377). May act as a receptor for pathogenic bacteria Neisseria and Streptococcus pyogenes(PubMed:7708671, PubMed:9379894, PubMed:11260136, PubMed:11971006).
