Binds to photoactivated, phosphorylated RHO and terminates RHO signaling via G-proteins by competing with G-proteins for the same binding site on RHO (PubMed:8003967, PubMed:25205354). May play a role in preventing light-dependent degeneration of retinal photoreceptor cells (By similarity).

Belongs to the arrestin family.
