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 that activates signaling via G-proteins. Subsequent receptor phosphorylation mediates displacement of the bound G-protein alpha subunit by the arrestin SAG and terminates signaling.

the rhodopsin is densely packed in the retina and the rhodopsin molecules are not aligned well.PMID:22842041
Phototransduction, even when initiated by wild type rhodopsin, is altered in a way progressive with level of retinal degeneration. A model introduces idea of binding site for carboxy terminus of rhodopsin on rhodopsin kinase.PMID:16402026
