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.. When interpreting results, consider species context, domain architecture, and whether the recombinant format represents full-length or a defined region.\u003c\/p\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eAntigen and virulence-factor studies that compare strain- or domain-specific binding and immune recognition.\u003c\/li\u003e\n\u003cli\u003eUse of recombinant proteins as standards for quantitative assays and serology-oriented method development.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBinding and interaction assays:\u003c\/strong\u003e quantify partner binding and rank conditions using plate-based formats or biophysical methods (SPR\/BLI).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnzymology:\u003c\/strong\u003e assess catalytic activity and compare substrate preferences or inhibitor effects using appropriate controls.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAssay development:\u003c\/strong\u003e use as a standard, spike-in control, or positive control where consistent specifications are required.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInterpretation typically relies on relative comparisons (treated vs control, mutant vs wild-type, or dose\/time series) using consistent sample handling and appropriate normalization.\u003c\/p\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePost-translational modifications:\u003c\/strong\u003e expression system can affect glycosylation and processing; interpret differences cautiously when comparing to native protein.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIsoforms and domains:\u003c\/strong\u003e expressed regions may not capture all isoform-specific features; match fragment boundaries to your assay’s binding site.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControls:\u003c\/strong\u003e include blank matrix controls, tag-only controls (where relevant), and orthogonal readouts (e.g., WB\/qPCR\/ELISA) to support interpretation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c!-- Sources (internal): - UniProt Knowledgebase entry for CD46 — UniProt — https:\/\/www.uniprot.org\/ - NCBI Gene for CD46 — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/ - RCSB Protein Data Bank — RCSB PDB — https:\/\/www.rcsb.org\/ - PubMed (reviews and primary literature) — NCBI — https:\/\/pubmed.ncbi.nlm.nih.gov\/ - Ensembl gene summary — Ensembl — https:\/\/www.ensembl.org\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53058998698349,"sku":"CSB-MP004939HUc7-1MG","price":2264.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53059105128813,"sku":"CSB-MP004939HUc7-100UG","price":372.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53059105161581,"sku":"CSB-MP004939HUc7-20UG","price":148.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-MP004939HUc7-SDS.jpg?v=1772271116","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-membrane-cofactor-protein-cd46-partial-bhp10511814","provider":"BioHippo","version":"1.0","type":"link"}
