Lipid Nanodomains Change Ion Channel Function

Abstract
Signaling proteins and neurotransmitter receptors associate with cholesterol-rich fractions of cell membranes--lipid rafts. The different lipid environment in rafts can modulate protein function, but evidence for modulation of ion channels is lacking. Here we show in a cholesterol-rich model membrane system that lipid phase properties at the nanoscale directly affect the dissociation kinetics of the gramicidin dimer, a model ion channel.Citation
