Question

Quizplus · Accepted Answer

Arrestins are a small group of proteins that bind to G protein-coupled receptors (GPCRs) and compete for binding with heterotrimeric G proteins. Upon activation of the GPCR, arrestins are recruited, leading to receptor desensitization and internalization. This helps regulate the signaling of GPCRs and prevent excessive signaling.
