Photoreceptor required for image-forming vision at low light intensity. Required for photoreceptor cell viability after birth. Light-induced isomerization of 11-cis to all-trans retinal triggers a conformational change leading to G-protein activation and release of all-trans retinal. Abs(max)=495 nm. Rod shaped photoreceptor cells which mediates vision in dim light. Phosphorylated on some or all of the serine and threonine residues present in the C-terminal region. Defects in RHO are the cause of retinitis pigmentosa type 4 (RP4). RP leads to degeneration of retinal photoreceptor cells. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well. RP4 inheritance is autosomal dominant. Defects in RHO are also a cause of retinitis pigmentosa autosomal recessive (ARRP). Also, defects in RHO are a cause of autosomal dominant congenital stationary night blindness 1 (CSNBAD1); also known as rhodopsin-related congenital stationary night blindness. Congenital stationary night blindness is a nonprogressive retinal disorder characterized by impaired night vision and ocular symptoms such as myopia, hyperopia, nystagmus and reduced visual acuity.
