Retinoids in the visual cycle: role of the retinal G protein-coupled receptor

Elliot H. Choi et al.

Summary: The text explains the isomerization process of visual pigments in rod and cone photoreceptor cells driven by photons, and the mechanism of visual signal transmission. It discusses the regeneration of retinoids achieved through a series of reactions, as well as the importance of RGR as an adjunct pathway.

Rhodopsins at a glance

Takashi Nagata et al.

Summary: Rhodopsins are a class of photoreceptive membrane proteins with a diverse range of functions, including microbial and animal rhodopsins. They exhibit distinctive characteristics in terms of function, structure, color discrimination mechanisms, and optogenetic applications, with a third rhodopsin family known as heliorhodopsin.

How does the skin sense sun light? An integrative view of light sensing molecules

Leonardo Vinicius Monteiro de Assis et al.

Summary: Human skin responses to sunlight involve both the beneficial and harmful effects of UV and visible light, which require a comprehensive understanding of the interactions of photons in the skin and the regulatory role of the light-sensing protein opsins.
