Opsins as main regulators of skin biology
Journal of Photochemistry and Photobiology, 2023 Opsins are light-sensitive proteins that are found across the animal kingdom. In mammals, opsins are classically associated with image-forming processes, a function exerted by cone and rod opsins.

A Large and Phylogenetically Diverse Class of Type 1 Opsins Lacking a Canonical Retinal Binding Site. [PDF]
PLoS ONE, 2016 Opsins are photosensitive proteins catalyzing light-dependent processes across the tree of life. For both microbial (type 1) and metazoan (type 2) opsins, photosensing depends upon covalent interaction between a retinal chromophore and a conserved lysine

Current Biology, 2002 What are opsins? Opsins are generally considered members of the superfamily of G-protein coupled receptors. But not all opsins activate a G-protein. Their distinguishing features are a 7 transmembrane α-helical structure, and an ability to bind a vitamin A chromophore, retinaldehyde, using a lysine in the 7th α-helix.

Creation of photocyclic vertebrate rhodopsin by single amino acid substitution
eLife, 2022 Opsins are universal photoreceptive proteins in animals and can be classified into three types based on their photoreaction properties. Upon light irradiation, vertebrate rhodopsin forms a metastable active state, which cannot revert back to the original

Pinopsin Regulates Melatonin Production and Daily Locomotor Activity: Functional Insights From Gene-Edited Xenopus Tadpoles. [PDF]
J Pineal ResABSTRACT Circadian rhythm alignment depends on environmental light detection via opsins. Pinopsin, originally identified in the pineal organ of birds and later in amphibian pineal complex and eyes, may play a role in this process, though its function has not been genetically tested.
