WebMar 19, 2024 · Allosteric communication in GPCRs Membrane-bound G protein-coupled receptors (GPCRs) are seven helical proteins that are expressed ubiquitously in multiple cells and hence form the largest family of drug targets. Upon activation by a ligand, GPCRs couple to one or more of the members of the G protein families and/or β-arrestin families.

WebApr 19, 2024 · The allosteric sodium ion effect was studied for all systems except for herkinorin. The herkinorin C2-benzyloxy group occupies the allosteric sodium site, near N150 3.35 [ 25 ]. In the absence of the allosteric sodium ion, the D 2.50 amino acid was set as protonated, as suggested in previous pKa studies of GPCRs [ 38 ]. Webcomprising the allosteric sodium pocket are highly conserved, these data likely provide fresh insights into regulation of G-pro-tein signaling by allosteric sodium-coordinating residues for many class A GPCRs and provide new tools for GPCR drug dis-covery.

WebThese new findings suggest that the sodium ion in the allosteric binding pocket not only impacts ligand affinity, but also plays a vital role in receptor signaling. Because the sodium ion binding pocket is highly conserved in other class A GPCRs, our findings may have a general relevance for these receptors and may guide the design of novel ...
