Critical role of RanBP2-mediated SUMOylation of Small Heterodimer Partner in maintaining bile acid homeostasis

Abstract

As signalling molecules, bile acids (BAs) can affect metabolism, but due to detergent-like properties, BA levels must be tightly regulated. Here, Kim et al.show that RanBP2, a nucleoporin, maintains BA homoeostasis through SUMOylation of Small Heterodimer Partner (SHP), an orphan nuclear receptor.
