Hepatic ß-arrestins: potential roles in liver health and disease.

Β-arrestins are intracellular scaffolding proteins that have multifaceted roles in different types of disorders. In this review article, we gave a summary about the discovery, characterization and classification of these proteins and their intracellular functions. Moreover, this review article focused on the hepatic expression of ß-arrestins and their hepatocellular distribution and function in each liver cell type. Also, we showed that ß-arrestins are key regulators of distinct types of hepatic disorders. On the other hand, we addressed some important points that have never been studied before regarding the role of ß-arrestins in certain types of hepatic disorders which needs more research efforts to cover.
