分子别名(Synonym)

CD46,AHUS2,MCP,MIC10,TLX,TRA2.10

表达区间及表达系统(Source)

Human CD46, His Tag (CD6-H5226) is expressed from human 293 cells (HEK293). It contains AA Cys 35 - Asp 328 (Accession # AAH30594.1).

Predicted N-terminus: Cys 35

蛋白结构(Molecular Characterization)

Online(Cys 35 - Asp 328) AAH30594.1

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 33.6 kDa. The protein migrates as 45-60 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>90% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

电泳(SDS-PAGE)

Human CD46, His Tag (Cat. No. CD6-H5226) SDS-PAGE gel

Human CD46, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.

背景(Background)

Complement regulatory protein CD46 is also known as membrane Cofactor Protein (MCP), is a type I membrane protein and is a regulatory part of the complement system. CD46 is expressed by all cells except erythrocytes. MCP 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, and also acts as a costimulatory factor for T-cells which induces the differentiation of CD4+ into T-regulatory 1 cells. In T-cells by binding to CD46, A number of viral and bacterial pathogens seem to exploit this property and directly induce an immunosuppressive phenotype. Defects in CD46 are a cause of susceptibility to hemolytic uremic syndrome atypical type 2 (AHUS2).
