Carboxypeptidase B2 (CPB2), also known as carboxypeptidase U (CPU), plasma carboxypeptidase B (pCPB) or thrombin-activatable fibrinolysis inhibitor (TAFI), is an enzyme that, in humans, is encoded by the gene CPB2. CPB2 is synthesized by the liver and circulates in the plasma as a plasminogen-bound zymogen. When it is activated by proteolysis at residue Arg92 by the thrombin\/thrombomodulin complex, CPB2 exhibits carboxypeptidase activity. Activated CPB2 reduces fibrinolysis by removing the fibrin C-terminal residues that are important for the binding and activation of plasminogen. Functional note: Cleaves C-terminal arginine or lysine residues from biologically active peptides such as kinins or anaphylatoxins in the circulation thereby regulating their activities. Down- regulates fibrinolysis by removing C-terminal lysine residues from fibrin that has already been partially degraded by plasmin. Reported localization: Secreted . Expression\/tissue context: Plasma; synthesized in the liver. .\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eCardiovascular: Researchers commonly examine how Cpb2 (Carboxypeptidase B2) relates to this theme using model systems and orthogonal readouts.\u003c\/li\u003e\n\u003cli\u003eHeart Disease: Researchers commonly examine how Cpb2 (Carboxypeptidase B2) relates to this theme using model systems and orthogonal readouts.\u003c\/li\u003e\n\u003cli\u003eMetabolic Signaling Pathways: Researchers commonly examine how Cpb2 (Carboxypeptidase B2) relates to this theme using model systems and orthogonal readouts.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eWestern blotting: compare relative Cpb2 (Carboxypeptidase B2) levels across conditions; band patterns may reflect isoforms and processing.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eSpecificity notes:\u003c\/strong\u003e No cross reactivity with other proteins.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eCross-reactivity:\u003c\/strong\u003e No cross-reactivity with other proteins\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eIsoforms and PTMs:\u003c\/strong\u003e Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eControls:\u003c\/strong\u003e Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD\/KO samples when available.\u003c\/li\u003e \u003c\/ul\u003e \u003c!-- Sources (internal): - UniProt entry for Q9JHH6: https:\/\/www.uniprot.org\/uniprotkb\/Q9JHH6\/entry - PubMed search (Cpb2): https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=Cpb2 - NCBI Gene search (Cpb2): https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=Cpb2 - Antibody validation concepts (NIH): https:\/\/www.nih.gov\/research-training\/rigor-reproducibility --\u003e","brand":"Boster Bio","offers":[{"title":"100 ug\/vial \/ Unconjugated","offer_id":53066841424237,"sku":"PB9998","price":370.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Biotin","offer_id":53067216683373,"sku":"PB9998-Biotin","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Cy3","offer_id":53067216716141,"sku":"PB9998-Cy3","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro488","offer_id":53067216748909,"sku":"PB9998-Fluoro488","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro550","offer_id":53067216781677,"sku":"PB9998-Fluoro550","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro594","offer_id":53067216814445,"sku":"PB9998-Fluoro594","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ FITC","offer_id":53067216847213,"sku":"PB9998-FITC","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ HRP","offer_id":53067216879981,"sku":"PB9998-HRP","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ APC","offer_id":53067216912749,"sku":"PB9998-APC","price":820.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ PE","offer_id":53067216945517,"sku":"PB9998-PE","price":820.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro647","offer_id":53067216978285,"sku":"PB9998-Fluoro647","price":670.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Carrier Free","offer_id":53067217011053,"sku":"PB9998-carrier-free","price":370.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/pb9998-1-WB-anti-tafi-cpb2-picoband-antibody.jpg?v=1772608232","url":"https:\/\/www.ebiohippo.com\/products\/anti-carboxypeptidase-b2-cpb2-antibody-picoband-bha21000903","provider":"BioHippo","version":"1.0","type":"link"}
