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, leading to the desensitization of the receptor. Arrestins also play a role in G protein-independent signaling pathways.
