|Application ||WB, IHC-P|
|Description||Rabbit IgG polyclonal antibody for Membrane cofactor protein(CD46) detection. Tested with WB, IHC-P in Human.|
|Reconstitution||Add 0.2ml of distilled water will yield a concentration of 500ug/ml.|
|Other Names||Membrane cofactor protein, TLX, Trophoblast leukocyte common antigen, CD46, CD46, MCP, MIC10|
|Calculated MW||43747 MW KDa|
|Application Details||Immunohistochemistry(Paraffin-embedded Section), 0.5-1 µg/ml, Human, By Heat|
Western blot, 0.1-0.5 µg/ml, Human
|Subcellular Localization||Cytoplasmic vesicle, secretory vesicle, acrosome inner membrane ; Single- pass type I membrane protein . 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 Specificity||Expressed by all cells except erythrocytes.|
|Protein Name||Membrane cofactor protein|
|Contents||Each vial contains 5mg BSA, 0.9mg NaCl, 0.2mg Na2HPO4, 0.05mg NaN3.|
|Immunogen||A synthetic peptide corresponding to a sequence at the C-terminus of human CD46 (366-392aa YRYLQRRKKKGTYLTDETHREVKFTSL).|
|Purification||Immunogen affinity purified.|
|Cross Reactivity||No cross reactivity with other proteins|
|Storage||At -20˚C for one year. After r˚Constitution, at 4˚C for one month. It˚Can also be aliquotted and stored frozen at -20˚C for a longer time.Avoid repeated freezing and thawing.|
|Sequence Similarities||Contains 4 Sushi (CCP/SCR) domains.|
|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.|

CD46 complement regulatory protein also known as CD46 (cluster of differentiation 46) and Membrane Cofactor Protein is a protein which in humans is encoded by the CD46 gene. The protein encoded by this gene is a type I membrane protein and is a regulatory part of the complement system. And 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.
