β-arrestins are intracellular proteins that play an important role in GPCR signaling. Complexes formed between ligand-occupied GPCRs and β-arrestin lead to interaction with adaptor protein AP2. This interaction is followed by internalization of the receptors. HTRF technology is effective for studying the interaction between AP2 and β-arrestin2.
