“…While the cross-talk is reproducible, it remains to be confirmed whether it occurs at the receptor level (i.e., dimerisation/oligomerisation) or further downstream. Indeed, McNeill and Zhao (2024) describe a family of downstream regulators of GPCR signalling, called regulator of G protein signalling (RGS) proteins, that have been implicated in cardiometabolic disorders. They argue that tissue-specific expression and selectivity for Gα protein subtypes makes the RGS family of intracellular proteins exciting therapeutic targets.…”
