Table 1. Non-classical functions of Drosophila opsins.
A list of fly opsins and their expression in classical photoreceptors in the adult compound eyes and ocelli, along with their non-classical functions outside of the eye.
| Flyopsin | Classical photoreceptors | Non-classical function |
|---|---|---|
| Rh1 | R1-R6 (outer) | thermosensation |
| Rh2 | ocelli | - |
| Rh3 | R7 (inner) | - |
| Rh4 | R7 (inner) | |
| Rh5 | R8 (inner) | thermosensation, hearing |
| Rh6 | R8 (inner) | thermosensation, hearing |
| Rh7 | - | circadian photoentrainment in central pacemaker neurons |
