CD46

CD46 molecule, complement regulatory protein

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. A number of viral and bacterial pathogens seem to exploit this property and directly induce an immunosuppressive phenotype in T-cells by binding to CD46.

Gene Name: CD46 molecule, complement regulatory protein
Synonyms: CD46, AHUS2, CD46 antigen, MCP, Measles virus receptor, TLX, MIC10, TRA2.10, Membrane cofactor protein
Target Sequences: NM_002389 NP_002380.3 P15529
