Unlike most μ-opioid agonists, herkinorin does not promote the recruitment of β-arrestin-2 to the intracellular domain of the μ-opioid receptor, or induce receptor internalization.
Za razliku od većine μ-opioidnih agonista, herkinorin ne promoviše regrutovanje β-arestina-2 na intracelularni domen μ-opioidnog receptora, niti indukuje internalizaciju receptora.
