Murine Myelin Basic Protein C8 Charge Isoform (MBP - rmMBP-C8)
This variant is pseudodeiminated rmMBP variant, rmMBP-C8, where five Arg and one Lys were substituted by Gln.
The intrinsically disordered, 18.5-kDa isoform of Myelin Basic Protein (MBP) is a peripheral membrane protein that is essential to proper myelin formation in the central nervous system. Unmodified MBP (C1 charge variant, the most abundant variant of the healthy human adult myelin) is an extremely positively charged protein (+19 at neutral pH). MBP acts in oligodendrocytes both to adjoin membrane leaflets to each other in forming compact myelin sheath and as a hub in numerous protein-protein and protein-membrane interaction networks. Interaction of MBP with its various partners may be mediated, in part, by post-translation modifications (PTMs) such as phosphorylation and deimination that result in charge reduction and are developmentally regulated. Distinct patterns of post-translational modifications, most notably excessive deimination, also occur in multiple sclerosis, leading to speculation that these aberrant PTMs are a part of the disease pathogenesis.
