Background: CD46

CD46, also known as MCP (Membrane cofactor protein), is a type I membrane protein that functions as a cofactor for Complement Factor I­mediated inactivation of complement components C3b and C4b (1, 2). Mature human CD46 consists of a 309 amino acid (aa) extracellular domain (ECD) with four short consensus repeats (SCR) and a Ser/Thr/Pro-enriched region, a 23 aa transmembrane domain, and a 26 aa cytoplasmic domain (1). Within the ECD, human CD46 shares 50% aa sequence identity with mouse and rat CD46. CD46 is commonly expressed in four distinct isoforms, and all isoforms have conserved complement control protein domains which harbor the C3b and C4b binding sites (3). CD46 is expressed on all nucleated cells (4). CD46 participates in the maintenance of immune homeostasis and the induction of protective T cell immunity, and it could extend towards key processes in development and cell metabolism (5).
