SAG 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. Retina and pineal gland. Belongs to the arrestin family. Note: This description may include information from UniProtKB.
