Background: CD46

CD46, also known as MCP, is a type I membrane protein that functions as a cofactor for Complement Factor I-mediated inactivation of complement components C3b and C4b. CD46 is expressed in white blood cells, platelets, epithelial cells, and fibroblasts. The extracellular region of CD46 contains four tandem Sushi domains. At least fourteen transcript variants encode isoforms with deletions or substitutions following the fourth Sushi domain. Within corresponding regions, human CD46 shares 50% amino acid sequence identity with mouse and rat CD46.
