Spatial Organization of Lipids Drives GPCR Conformational Equilibria

Anuradha V. Wijesekara, Jing-Jing Ji, Nessa Pesaran Afsharian, Keen Zhang, Naveen Thakur, Arka Prabha Ray, Bar Elmaleh, Niloofar Gopal Pour, Edward R. Lyman, Matthew T. Eddy

The paper investigates how lipid organization in nanodiscs affects GPCR conformational states, finding that anionic lipid concentration thresholds vary between POPS and POPG.

The conformational equilibria of a human GPCR compared between lipid vesicles and aqueous solutions by integrative 19F-NMR

Arka Prabha Ray, Beining Jin, Matthew T. Eddy

This study compares the conformational equilibria of the human A2A adenosine receptor in lipid vesicles and aqueous solutions using 19F-NMR, revealing environment-dependent differences in agonist-bound states.
