Abstract
Crystallographic studies of visual arrestin in the late nineties built upon fundamental biochemical work that had identified arrestins as proteins central to desensitization of GPCR signaling. The structural findings revealed the arrestin fold that had two related domains and a C-tail, which folded onto the molecule's surface. The structures had a curious "polar core" that sat at the fulcrum of the two domains and which acts as an active site for conformational activation. The structures also served as the basis for elaborating the arrestin fold, found in all the kingdoms of life. Finally, the results suggested that quaternary structure i.e. The oligomeric state played a role in self-regulation.
