Application

It has been studied as a generator of peptides responsible for biological activities such as opiate, immunostimulating, antibacterial, and peptidase inhibitors.

β-Casein from bovine milk has been used as a protein substrate in proteolytic assays. It has also been used to embed polyacrylamide gels in β-casein zymography.

Biochem/physiol Actions

A polymorphic fraction of the major milk protein, casein. The A1 and B (but not A2) isoforms yield the bioactive peptide, ß-casomorphin upon gastrointestinal proteolytic digestion, which can have widely varied effects on human health. There is some effort to select dairy cattle for the A2 isoform to avoid this possibility.

General description

β-Casein from bovine milk is an immunoglobulin E (IgE)-binding epitope belonging to the secretory calcium-binding phosphoprotein family. It consists of 209 amino acids and five phosphate groups. β-Casein has a globular hydrophobic domain at the C-terminal, a highly solvated and charged domain at the N-terminal and proline residues.
