CPA1 comprises a signal peptide, a pro region and a mature chain, and can be activated after cleavage of the pro peptide. In contrast to procarboxypeptidase B which was always secreted by the pancreas as a monomer, procarboxypeptidase A occurs as a monomer and\/or associated to one or two functionally different proteins, such as zymogen E, and is involved in zymogen inhibition. Three different forms of human pancreatic procarboxypeptidase A have been isolated.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Elabscience Biotechnology","offers":[{"title":"50μg","offer_id":40727388127290,"sku":"PKSH031565-50","price":1024.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0722\/7785\/files\/recombinant-human-carboxypeptidase-a1-cpa1-protein-his-tag-active-50-g-elabscience-biotechnology-cell-assays-22470996754490.jpg?v=1752495945","url":"https:\/\/www.msesupplies.com\/products\/recombinant-human-carboxypeptidase-a1-cpa1-protein-his-tag-active","provider":"MSE Supplies","version":"1.0","type":"link"}
