Description

This peptide constitutes the acetylated N-terminal region of murine myelin basic protein (MBP) and displays high affinity for major histocompatibility complexes (MHC). This high MHC affinity is due to substitution of the native lysine at position 4 for a tyrosine. Substitution increases the MHC binding affinity of the peptide by around 1 million fold, therefore creating a superagonist ligand. MBP is an integral component of myelin found in the central nervous system (CNS) vital for the development and stability of the myelin sheath where it plays a role in membrane adhesion. MBP may be targeted by auto-antibodies in diseases such as multiple sclerosis. The low affinity of the native lysine containing MBP 1-9 peptide for MCH class II may result in MBP auto-reactive T cells escaping central-tolerance where self reactive T cells are usually eliminated. MBPs constitute an extraordinarily varied collection of splice isoforms which show a myriad of post-translational modifications.
