G protein-coupled receptors (GPCRs) are a vast family of membrane-bound proteins crucial for transmitting Traditionally, it was believed that GPCRs selectively activate only their cognate G protein subtypes, 'unproductive coupling'[1] and a fascinating phenomenon known as GPCR priming [2]. The enhanced signalling observed in GPCR priming is attributed to the formation of temporal non-cognate-GPCR GPCR priming opens new avenues for understanding the nuanced regulatory mechanisms governing GPCR signalling
