abstractText | Central nervous system myelin is a dynamic entity arising from membrane processes extended from oligodendrocytes, which form a tightly-wrapped multilamellar structure around neurons. In mature myelin, the predominant splice isoform of classic MBP is 18.5kDa. In solution, MBP is an extended, intrinsically disordered protein with a large effective protein surface for myriad interactions, and possesses transient and/or induced ordered secondary structure elements for molecular association or recognition. Here, we show by nanopore analysis that the divalent cations copper and zinc induce a compaction of the extended protein in vitro, suggestive of a tertiary conformation that may reflect its arrangement in myelin. |
