Interaction of myelin basic protein with gangliosides and ganglioside-phospholipid mixtures

The interaction of myelin basic protein with monosialoganglioside GM1 was investigated. It was found that the emission maximum of the tryptophan of the protein is blue-shifted due to the interaction. In mixtures of the monosialoganglioside with phosphatidylcholine, the myelin basic protein induces phase separation of the lipids as inferred from differential scanning calorimetry experiments.
