background

CD46 was discovered in 1986 during a search for novel C3b-binding proteins. CD46 is expressed ubiquitously and functions as a co-factor in the factor I-mediated proteolytic cleavage of C3b and C4b. Its vital role in preventing complement deposition on host tissue is underpinned by the fact that deficiency of CD46 is a predisposing factor for numerous disease conditions arising from complement-mediated 'self-attack'.

molecular weight

The protein has a predicted MW of 35.4 kDa. Due to glycosylation, the protein migrates to 60-70 kDa based on Tris-Bis PAGE result.

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.; (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 (PubMed:7708671, PubMed:9379894, PubMed:11260136, PubMed:11971006).
Subellular location
Cytoplasmic vesicle, secretory vesicle, acrosome inner membrane ; Single-pass type I membrane protein. Note=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.
Tissues
Expressed by all cells except erythrocytes.
Structure
Interacts with C3b (PubMed:3260937, PubMed:1717583). Interacts with C4b (PubMed:1717583). Interacts with moesin/MSN (PubMed:7884872).; (Microbial infection) Interacts with measles virus H protein.; (Microbial infection) Interacts with human herpesvirus 6 GH protein (PubMed:12663806, PubMed:12724329).; (Microbial infection) Interacts with human adenovirus B/D fiber protein (PubMed:12915534, PubMed:14566335, PubMed:15047806, PubMed:15078926, PubMed:15919905, PubMed:16254377).; (Microbial infection) Binds to Streptococcus pyogenes M protein and to type IV pili from Neisseria (PubMed:7708671, PubMed:9379894, PubMed:11260136, PubMed:11971006).
Post-translational modification
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.
