a G-protein coupled receptor. The light-absorbing visual pigment in Rod photoreceptor cells. Mediates vision in dim light. Consists of the apoprotein, opsin, covalently linked to cis-retinal. Defects in RHO are a cause of autosomal retinitis pigmentosa and congenital stationary night blindness. Note: This description may include information from UniProtKB.
