Abstract

The classic 18.5 kDa isoform of myelin basic protein (MBP) is central to maintaining the structural homeostasis of the myelin sheath of the central nervous system. It is an intrinsically disordered, promiscuous, multifunctional, peripheral membrane protein, whose conformation adapts to its particular environment. Its study requires the selective and complementary application of diverse approaches, of which solution and solid-state NMR spectroscopy are the most powerful to elucidate site-specific features. We review here several recent solution and solid-state NMR spectroscopic studies of 18.5 kDa MBP, and the induced partial disorder-to-order transitions that it has been demonstrated to undergo when complexed with calmodulin, actin, and phospholipid membranes.
