Structural and dynamic studies of the gamma-M4 trans-membrane domain of the nicotinic acetylcholine receptor.

abstract：:Membrane microdomains enriched in cholesterol, sphingolipids (rafts), and specific proteins are involved in important physiological functions. However their structure, size and stability are still controversial. Given that detergent-resistant membranes (DRMs) are in the liquid-ordered state and are rich in raft-like c...
