CELL SIGNALING:
β-Arrestin--Not Just for G Protein-Coupled Receptors

Allen Spiegel

The beta-arrestin adaptor proteins are known to mediate the endocytosis of G protein-coupled receptors. In this way, they down-regulate the activated receptors ensuring that they are degraded or recycled within the cell. As Spiegel explains in his Perspective, it now turns out that beta-arrestins are also important for the endocytosis and down-regulation of a variety of other receptors including Frizzled 4 and TGF-beta-receptors, II and III (Chen et al., Chen et al.).
