==ARRESTIN FROM BOVINE ROD OUTER SEGMENTS==
-
Retinal arrestin is the essential protein for the termination of the light, response in vertebrate rod outer segments. It plays an important role in, quenching the light-induced enzyme cascade by its ability to bind to, phosphorylated light-activated rhodopsin (P-Rh*). Arrestins are found in, various G-protein-coupled amplification cascades. Here we report on the, three-dimensional structure of bovine arrestin (relative molecular mass, 45,300) at 3.3 A resolution. The crystal structure comprises two domains, of antiparallel beta-sheets connected through a hinge region and one short, alpha-helix on the back of the amino-terminal fold. The binding region for, phosphorylated light-activated rhodopsin is located at the N-terminal, domain, as indicated by the docking of the photoreceptor to the, three-dimensional structure of arrestin. This agrees with the, interpretation of binding studies on partially digested and mutated, arrestin.

== Function ==
 +
[https://www.uniprot.org/uniprot/ARRS_BOVIN ARRS_BOVIN] Arrestin is one of the major proteins of the ros (retinal rod outer segments); it binds to photoactivated-phosphorylated rhodopsin, thereby apparently preventing the transducin-mediated activation of phosphodiesterase. Isoform B plays a role in the phototransduction cascade.
