靶點詳情

功能：

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.; (Microbial infection) Acts as a receptor for Adenovirus subgroup B2 and Ad3.; (Microbial infection) Acts as a receptor for cultured Measles virus.; (Microbial infection) Acts as a receptor for Herpesvirus 6/HHV-6.; (Microbial infection) May act as a receptor for pathogenic bacteria Neisseria and Streptococcus pyogenes.
