– Important role in determination of the surface properties of the casein micelles.; Casoparan acts as a macrophage activator, increasing the phagocytic activity of macrophages and peroxide release from macrophages. It also acts as a bradykinin-potentiating peptide.; Casohypotensin acts as a bradykinin-potentiating peptide. Induces hypotension in rats. Acts as a strong competitive inhibitor of endo-oligopeptidase A.; Antioxidant peptide has antioxidant activity. Beta-casein Protein, Bovine, Recombinant (His & Myc) is expressed in E. coli expression system with N-10xHis and C-Myc tag. The predicted molecular weight is 28.6 kDa and the accession number is P02666.
