From: The orientation and stability of the GPCR-Arrestin complex in a lipid bilayer
The orientation of rhodopsin and arrestin before and after the complex formation. All data from rhodopsin alone or arrestin alone were plotted with black lines, data from rhodopsin in complex or arrestin in complex were plotted with red lines. (a) The rhodopsin orientation change was subtle upon the formation of the complex. (b) The probability distribution of the angle between the first principal axis of rhodopsin and the Z-axis, before (top) and after (bottom) the complex formation. (c) The arrestin orientation was limited to a much smaller range upon the complex formation. (d) same as (b), but for arrestin.
