Background Information

Arrestin C, also known as Arrestin 3 or Retinal Cone Arrestin, is a protein encoded by the ARR3 gene. It belongs to the arrestin family, which plays a crucial role in regulating G-protein-coupled receptor (GPCR) signaling and trafficking. Arrestin C is composed of two major domains: the N-domain and the C-domain, connected by a hinge region. These domains form a structure resembling two clamshells placed end-to-end. The C-terminal tail (C-tail) of Arrestin C interacts extensively with the N-domain, stabilizing its basal conformation. Arrestin C is predominantly expressed in cone photoreceptors and pinealocytes in the retina. It is involved in the shut-off mechanisms associated with high-acuity color vision by binding to phosphorylated and activated opsins, thereby inhibiting their ability to interact with transducin.
