Abstract:
The most robust entrainment cue to the circadian clock is light. In response to this, organisms have evolved light detection mechanisms which allow them to measure and transduce irradiance information to specific centres in the brain. To perceive light, these receptors use photosensitive opsins that are remarkably divergent from those involved in image-forming photoreception. The main focus of this work was to understand if the photopigment function of the inner-retinal opsins can be inferred from their sequence and predicted structure. To this end we have isolated and characterised melanopsin and VA opsin from vertebrate species that have evolved under different environments.
