General annotation (Comments)

Function

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 By similarity.

Subunit structure

Homodimer By similarity.

Subcellular location

Membrane; Multi-pass membrane protein. Note: Synthesized in the inner segment (IS) of rod photoreceptor cells before vectorial transport to the rod outer segment (OS) photosensory cilia By similarity.

Tissue specificity

Rod shaped photoreceptor cells which mediates vision in dim light.

Post-translational modification

Contains one covalently linked retinal chromophore By similarity.

Sequence similarities

Belongs to the G-protein coupled receptor 1 family. Opsin subfamily.

Biophysicochemical properties

Absorption:

Abs(max)=495 nm
