cGMP-gated cation channel alpha-1; Subunit of the rod cyclic GMP-gated cation channel, which is involved in the final stage of the phototransduction pathway. When light hits rod photoreceptors, cGMP concentrations decrease causing rapid closure of CNGA1/CNGB1 channels and, therefore, hyperpolarization of the membrane potential.

Cyclic nucleotide gated channel subunit beta 1.

Arrestin 3.

Guanylate cyclase.

Guanylate cyclase domain-containing protein.

Solute carrier family 24 member 2; Belongs to the Ca(2+):cation antiporter (CaCA) (TC 2.A.19) family.

Cyclic nucleotide-gated cation channel beta-3; Visual signal transduction is mediated by a G-protein coupled cascade using cGMP as second messenger. This protein can be activated by cGMP which leads to an opening of the cation channel and thereby causing a depolarization of rod photoreceptors. Induced a flickering channel gating, weakened the outward rectification in the presence of extracellular calcium, increased sensitivity for L-cis diltiazem and enhanced the cAMP efficacy of the channel when coexpressed with CNGA3. Essential for the generation of light-evoked electrical responses [...]

Long-wave-sensitive opsin 1; Visual pigments are the light-absorbing molecules that mediate vision. They consist of an apoprotein, opsin, covalently linked to cis-retinal; Belongs to the G-protein coupled receptor 1 family. Opsin subfamily.

Retinal guanylyl cyclase 1; Catalyzes the synthesis of cyclic GMP (cGMP) in rods and cones of photoreceptors. Plays an essential role in phototransduction, by mediating cGMP replenishment. May also participate in the trafficking of membrane-associated proteins to the photoreceptor outer segment membrane.
