Phosphopeptides are modified self antigens which may induce an immune response. Protein phosphorylation is a very important and frequent post-translational modification that can impact a protein's localization, stability, and whether or not it can dimerize or form stable bonds with other substances. It is vital to pinpoint which amino acid in ... WebThe casein phosphopeptides (CPP) are derived from the milk protein casein by tryptic digestion. The CPP, containing the sequence -Pse-Pse-Pse-Glu-Glu- where Pse is a phosphoseryl residue, stabilize calcium and phosphate ions in aqueous solution and make these essential nutrients bioavailable.
