產品描述：

The DNA fragment encoding the human CD46 (Cys35-Tyr328) was expressed with a C-terminal hFc-tag in the mammalian cells. The expressed protein is the recombinant human CD46 protein with low endotoxin (< 1.0 EU/µg protein, LAL method) and high purity (> 92%, SDS-PAGE). This CD46 protein displayed a molecular weight of approximately 90 kDa on the gel due to glycosylation. It is biologically active. In the functional ELISA, this CD46 protein can bind to the anti-CD46 antibody with an EC₅₀ of 0.8333-1.054 ng/ml. This recombinant CD46 protein is in stock now.

CD46 is ubiquitously expressed, alternatively spliced complement regulatory protein. It acts as a cofactor for the serine protease factor I to mediate the interaction of C3b and C4b deposited on host cells, thus protecting host cells from injury. CD46 also modulates adaptive immunity and participates in human infectious and Th1 biology. Increased expression of CD46 has been found in many types of cancer.

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.
