| Description | CD46 molecule(CD46) Homo sapiens The protein encoded by this gene is a type I membrane protein and is a regulatory part of the complement system. The encoded protein has cofactor activity for inactivation of complement components C3b and C4b by serum factor I, which protects the host cell from damage by complement. In addition, the encoded protein can act as a receptor for the Edmonston strain of measles virus, human herpesvirus-6, and type IV pili of pathogenic Neisseria. Finally, the protein encoded by this gene may be involved in the fusion of the spermatozoa with the oocyte during fertilization. Mutations at this locus have been associated with susceptibility to hemolytic uremic syndrome. Alternatively spliced transcript variants encoding different isoforms have been described.

| Protein Function | Additional isoforms seem to exist. The complete sequences of the isoforms are not known. Isoforms are classified as alpha (isoform C and isoform D), beta (isoform E and isoform F), gamma (isoform A and isoform B) and delta (isoform N). Isoforms gamma are preferentially expressed in EBV-B cells and leukemic cells. Isoforms alpha (66 kDa) and isoforms beta (56 kDa) are found in all tissues except sperm. Isoform delta is expressed in spermatozoa. The exon 9 is specifically deleted in some placentae isoforms. All tissues differentially splice exon 13,disease:Defects in CD46 are a cause of atypical hemolytic-uremic syndrome (HUS) [MIM:235400]. HUS is a microvasculature disorder leading to microangiopathic hemolytic anemia associated with distorted erythrocytes ('burr cells'), thrombocytopenia, and acute renal failure. Both dominant and recessive modes of inheritance have been reported. Most cases of HUS are associated with epidemics of diarrhea caused by verocytotoxin-producing bacteria, but atypical cases of HUS not associated with diarrhea (aHUS) also occur.,disease:Specific defects in the sperm forms of CD46 were found in 3 infertile patients.,domain:Sushi domains 1 and 2 are required for interaction with human adenovirus B PIV/FIBER protein and with Measles virus H protein. Sushi domains 2 and 3 are required for Herpesvirus 6 binding. Sushi domain 3 is required for Neisseria binding. Sushi domains 3 and 4 are required for interaction with Streptococcus pyogenes M protein and are the most important for interaction with C3b and C4b.,function: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.,PTM:Extensively O-glycosylated in the Ser/Thr-rich domain. O-glycosylation is required for Neisseria binding but not for Measles virus or human adenovirus binding.,PTM:In epithelial cells, isoforms B/D/F/H/J/L/3 are phosphorylated by YES1 in response to infection by Neisseria gonorrhoeae; which promotes infectivity. In T-cells, these isoforms may be phosphorylated by Lck.,PTM:N-glycosylated on Asn-83; Asn-114 and Asn-273 in most tissues, but probably less N-glycosylated in testis. N-glycosylation on Asn-114 and Asn-273 is required for cytoprotective function. N-glycosylation on Asn-114 is required for Measles virus binding. N-glycosylation on Asn-273 is required for Neisseria binding. N-glycosylation is not required for human adenovirus binding.,similarity:Contains 4 Sushi (CCP/SCR) domains.,subcellular location:Inner acrosomal membrane of spermatozoa. Internalized upon binding of Measles virus, Herpesvirus 6 or Neisseria gonorrhoeae, which results in an increased susceptibility of infected cells to complement-mediated injury. In cancer cells or cells infected by Neisseria, shedding leads to a soluble peptide.,subunit:Interacts with C3b and C4b. Binds to Measles virus H protein, to Human herpesvirus 6 GH protein and to human adenovirus B/D PIV/fiber protein, and acts as a receptor for these viruses. Binds to Streptococcus pyogenes M protein and to type IV pili from Neisseria, and may act as a receptor for these pathogenic bacteria.,tissue specificity:Expressed by all cells except erythrocytes., |
