Description
CD46 Antibody is a Rabbit Polyclonal antibody against CD46. CD46 is a type I membrane protein and a regulatory part of the complement system. This protein has cofactor activity for inactivation of complement components C3b and C4b by serum factor I, which protects the host cell from damage by complement. In addition, CD46 can act as a receptor for the Edmonston strain of measles virus, human herpesvirus-6, and type IV pili of pathogenic Neisseria. Finally, this protein may be involved in the fusion of the spermatozoa with the oocyte during fertilization. CD46 is found in a cluster on chromosome 1q32 with other proteins that are structural components of the complement system. Entrez Gene: gene-centered information at NCBI.

Background
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.
