Abstract excerpt
After protracted stimulation, the β2-adrenergic receptor and many other G-protein-coupled receptors are ubiquitinated and down-regulated. Arrestin-related domain-containing protein-3 (ARRDC3) has been proposed to recruit the ubiquitin ligase Nedd4 to the β2-adrenergic receptor. ARRDC3 contains two PPXY motifs that could potentially interact with any of the four WW domains of Nedd4. Here we dissect the interaction...
