The co-expression of visual pigments in a single photoreceptor: environmental regulation and spectral tuning (2003)

Abstract:
The light sensitive cells (photoreceptors) in the vertebrate retina contain filters (oil droplets) and visual pigments (opsins). These structures tune the incoming light and initiate the visual process, respectively. Exciting new research reveals that some vertebrates express more than one opsin within a single photoreceptor. We plan to examine the regulation of single and two co-expressed opsin genes by manipulating the light environment. We expect to determine the environmental triggers for visual pigment tuning and the effects of co-expression on colour vision. ''
