|Title:||Effects of trifluoperazine on the conformation and dynamics of membrane proteins in human erythrocytes|
|Abstract:||The chemical modifications induced by trifluoperazine (TFP) in erythrocyte ghosts have been investigated by fluorescence quenching. The apparent distance separating the membrane protein tryptophans and bound 1-aniline-8-naphthalene sulfonate (ANS) molecules decreased after treating erythrocyte membranes with TFP. This effect was accompanied by a significant decrease in the maximum efficiency of energy transfer. We conclude that TFP-induced alterations in the structure of membrane proteins lead to a rearrangement of the surrounding lipids, and consequently to local conformational changes in membrane organization.
