Functioni

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.2 Publications
(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. Acts as a receptor for adenovirus subgroup B2 and Ad3, cultured measles virus and herpesvirus 6 (PubMed:10972291, PubMed:12663806, PubMed:12724329, PubMed:12915534, PubMed:14566335, PubMed:15047806, PubMed:15078926, PubMed:15919905, PubMed:16254377). May act as a receptor for pathogenic bacteria Neisseria and Streptococcus pyogenes (PubMed:7708671, PubMed:9379894, PubMed:11260136, PubMed:11971006).13 Publications

Involvement in diseasei

Hemolytic uremic syndrome atypical 2 (AHUS2)4 Publications
Disease susceptibility is associated with variations affecting the gene represented in this entry. 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.
Disease descriptionAn 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.

Post-translational modificationi

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.
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.
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.

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.

This entry describes 16 isoformsi produced by alternative splicing. AlignAdd to basket

Note: 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.

Also known as: no del, ABC1

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
