Research suggests it may influence the transition into deeper rest stages by interacting with pathways that govern sleep architecture, while separate findings explore its role in modulating corticotropin-releasing factor activity, a key driver of the bodys stress hormone response, to encourage a calmer and more balanced internal environment conducive to overnight restoration

Role of arrestins in OR regulation From the canonical model of GPCR regulation by Lefkowitz, arrestins (arrestins 2 and 3 also named -arrestins 1 and 2, respectively) play a pivotal role in receptor regulation by promoting G protein uncoupling and receptor endocytosis (Pierce et al., 2002)

27 These modalities influence ion channel activity, increasing intracellular calcium levels, which are crucial for activating downstream signaling pathways such as calcineurin/NFAT, leading to increased protein synthesis, growth factor production, and accelerated tissue repair
