Summary
Phototransduction, the process of light detection by retinal cells, is explained by a G-protein cascade. This cascade
Area of Science:
- Biochemistry
- Molecular Biology
- Neuroscience
Background:
- Phototransduction is the process by which light triggers a neural response in retinal rod and cone photoreceptors.
- The G-protein cascade involved in phototransduction is a well-understood biological signaling pathway.
- Understanding the diffusional interactions of proteins in this cascade is key to explaining photoreceptor function.
