[[http://www.uniprot.org/uniprot/MCP_HUMAN MCP_HUMAN]] Defects in CD46 are a cause of susceptibility to hemolytic uremic syndrome atypical type 2 (AHUS2) [MIM:[http://omim.org/entry/612922 612922]]. An atypical form of hemolytic uremic syndrome. It is a complex genetic disease characterized by microangiopathic hemolytic anemia, thrombocytopenia, renal failure and absence of episodes of enterocolitis and diarrhea. In contrast to typical hemolytic uremic syndrome, atypical forms have a poorer prognosis, with higher death rates and frequent progression to end-stage renal disease. Note=Susceptibility to the development of atypical hemolytic uremic syndrome can be conferred by mutations in various components of or regulatory factors in the complement cascade system. Other genes may play a role in modifying the phenotype. Patients with CD46 mutations seem to have an overall better prognosis compared to patients carrying CFH mutations.<ref>PMID:14615110</ref> <ref>PMID:14566051</ref> <ref>PMID:16621965</ref> <ref>PMID:16386793</ref> <ref>PMID:20513133</ref>

[[http://www.uniprot.org/uniprot/FIBP_ADE1P FIBP_ADE1P]] Forms spikes that protrude from each vertex of the icosahedral capsid. Interacts with host receptor CD46 to provide virion initial attachment to target cell. Fiber proteins are shed during virus entry, when virus is still at the cell surface. [[http://www.uniprot.org/uniprot/MCP_HUMAN MCP_HUMAN]] 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.<ref>PMID:10843656</ref> <ref>PMID:12540904</ref> 
[https://www.uniprot.org/uniprot/SPIKE_ADE1P SPIKE_ADE1P] Forms spikes that protrude from each vertex of the icosahedral capsid. Interacts with host receptor CD46 to provide virion initial attachment to target cell. Fiber proteins are shed during virus entry, when virus is still at the cell surface.
