Cell Membrane Composition Affects GPCR Aggregation [PDF]

open access: yesBiophysical Journal, 2014
Recent experimental studies demonstrate that membrane composition is altered in certain human disorders. Modifying membrane composition (e.g. varying the concentration of cholesterol or certain phospholipid species) could in turn affect the behaviour of transmembrane proteins such as G protein-coupled receptors (GPCRs).
