S-arrestin, Recombinant, Human, aa1-405, His-Tag (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. Source: Recombinant protein corresponding to aa1-405 from human SAG, fused to His-Tag at N-terminal, expressed in Yeast.
