How GPCRs use phosphorylation codes for arrestin recruitment
DEER spectroscopy by Ned van Eps in the Ernst lab was used to validate the crystal structure of the phosphorylated G-protein-coupled receptor (GPCR) rhodopsin in complex with arrestin. EPR measurements confirmed the location of the C-terminal tail of rhodopsin on a arrestin binding surface in a non-crystallographic environment. GPCRs are among the most important cell surface receptors controlling nearly all of our physiology. Termination of G-protein-mediated signalling by an […]
