  • WB - CD46 Antibody (C-term) AW5239-U400
    Western blot analysis of lysates from SK-BR-3,Jurkat cell line (from left to right), using CD46 Antibody (C-term)(Cat. #AW5239). AW5239 was diluted at 1:1000 at each lane. A goat anti-rabbit IgG H&L(HRP) at 1:10000 dilution was used as the secondary antibody.
  • IHC-P - CD46 Antibody (C-term) AW5239-U400
    CD46 Antibody (C-term) (Cat. #AW5239) immunohistochemistry analysis in formalin fixed and paraffin embedded human hepatocarcinoma followed by peroxidase conjugation of the secondary antibody and DAB staining. This data demonstrates the use of the CD46 Antibody (C-term) for immunohistochemistry. Clinical relevance has not been evaluated.
  • FC - CD46 Antibody (C-term) AW5239-U400
    CD46 Antibody (C-term) (Cat. #AW5239) flow cytometric analysis of CEM cells (right histogram) compared to a negative control cell (left histogram).FITC-conjugated goat-anti-rabbit secondary antibodies were used for the analysis.
  • IF - CD46 Antibody (C-term) AW5239-U400
    Confocal immunofluorescent analysis of CD46 Antibody (C-term) (Cat. #AW5239) with Hela cell followed by Alexa Fluor® 489-conjugated goat anti-rabbit lgG (green). DAPI was used to stain the cell nuclear (blue).

PrecautionsCD46 Antibody (C-term) is for research use only and not for use in diagnostic or therapeutic procedures.
Protein Information
Name CD46
Synonyms MCP, MIC10
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.
Cellular 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
Tissue Location Expressed by all cells except erythrocytes.

CD46 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. This gene is found in a cluster on chromosome 1q32 with other genes encoding structural components of the complement system.
