Distinct G protein-coupled receptor phosphorylation motifs modulate arrestin affinity and activation and global conformation

Distinct G protein-coupled receptor phosphorylation motifs modulate arrestin affinity and activation and global conformation

The cellular functions of arrestins are determined in part by the pattern of phosphorylation on the G protein-coupled receptors (GPCRs) to which arrestins bind. Here, authors use a library of synthetic phosphopeptide analogues of the GPCR rhodopsin C-terminus and determine the ability of these pepti...

Sumario:The cellular functions of arrestins are determined in part by the pattern of phosphorylation on the G protein-coupled receptors (GPCRs) to which arrestins bind. Here, authors use a library of synthetic phosphopeptide analogues of the GPCR rhodopsin C-terminus and determine the ability of these peptides to bind and activate arrestins using a variety of biochemical and biophysical methods.
