Rhodopsin 5 (Rh5) encodes a visual GPCR opsin that covalently binds the chromophore retinal. A photon of light stimulates the isomerization of retinal resulting in a conformational change in the product of Rh5 and signal activation. Its peak sensitivity is in the blue and it is expressed in a subclass of R8 photoreceptors; Belongs to the G-protein coupled receptor 1 family. Opsin subfamily.

Rhodopsin 3 (Rh3) encodes a Rhodopsin GPCR protein that responds to UV light and activates the phototransduction cascade that leads to photoreceptor depolarization. Rh3 is expressed in R7 photoreceptors in a stochastic manner: 35% of R7 photoreceptors express Rh3 while the remaining 65% express another UV-sensitive Rhodopsin encoded by Rh4.

PIP82; It is involved in the biological process described with: cellular response to light stimulus.

Glass (gl) encodes a zinc finger transcription factor involved in cell fate specification. It is primarily transcribed in photoreceptors, where its expression is activated by the retinal determination member encoded by so. gl is required for correctly patterning the retina, rhabdomere formation, and for the expression of phototransduction proteins.

Opsin Rh4; Visual pigments are the light-absorbing molecules that mediate vision. They consist of an apoprotein, opsin, covalently linked to cis-retinal.

Defective proventriculus (dve) encodes a transcriptional repressor that binds to the K50 site. It is involved in developmental patterning, cell-type specification, and functional differentiation.

Opsin Rh1; Neither inactivation nor afterpotential E (ninaE) encodes a protein that plays a major role in light detection and vision. It is the rhodopsin expressed in the largest class of photoreceptors in the adult retina. The stimulation by light of the product of ninaE induces G-protein signaling activation, the opening of the channels encoded by trp and trpl and photoreceptor cell membrane depolarization.

Protein eyes shut; Essential for the formation of matrix-filled interrhabdomeral space: critical for the formation of epithelial lumina in the retina. Acts together with prominin (prom) and the cell adhesion molecule chaoptin (chp) to choreograph the partitioning of rhabdomeres into an open system.

Rhodopsin 2 (Rh2) encodes a light sensitive GPCR Rhodopsin protein that activates the phototransduction cascade and leads to photoreceptor depolarization. It responds to a broad spectrum of wavelengths of light and is exclusively expressed in the ocelli, which are likely involved in horizon detection.
