Opsin vs opsin: New materials for biotechnological applications [PDF]
Journal of Applied Physics, 2014 The need of new diagnostic methods satisfying, as an early detection, a low invasive procedure and a cost-efficient value, is orienting the technological research toward the use of bio-integrated devices, in particular, bio-sensors. The set of know-why necessary to achieve this goal is wide, from biochemistry to electronics and is summarized in an ...

Molecular evolution and expression of opsin genes in Hydra vulgaris [PDF]
BMC Genomics, 2019 Background The evolution of opsin genes is of great interest because it can provide insight into the evolution of light detection and vision. An interesting group in which to study opsins is Cnidaria because it is a basal phylum sister to Bilateria with ...

Stimulation-Guided AAV Delivery and Longitudinal Assessment of Optogenetic Expression in Rat Motor Nerves [PDF]
Bio-ProtocolOptogenetic stimulation of peripheral motor nerves is a promising technique for modulating neural activity via illumination of light-sensitive ion channels known as opsins. Stimulating muscle activity through this method offers many advantages, such as a

Genome Biol EvolAbstract In this study, we explored the diversity and evolution of opsins using meta-omic data from the Tara Oceans and Tara Polar Circle expeditions, one of the largest marine datasets available. By using sequence similarity methods and phylogenetic analyses, we identified opsins across the different metazoan groups.

Broad-Band Activatable White-Opsin.
PLoS ONE, 2015 Currently, the use of optogenetic sensitization of retinal cells combined with activation/inhibition has the potential to be an alternative to retinal implants that would require electrodes inside every single neuron for high visual resolution.

Elimination of Ultraviolet Light-Mediated Attraction Behavior in Culex Mosquitoes via dsRNA-Mediated Knockdown of Opsins [PDF]
InsectsIt is widely recognized that mosquitoes are attracted to ultraviolet (UV) light traps in field and semi-field trials. However, the specific characteristics of mosquito behavioral responses to UV light remain poorly defined.

Molecular Biology and Evolution, 2022 Abstract Opsins, the protein moieties of animal visual photo-pigments, have emerged as moonlighting proteins with diverse, light-dependent and -independent physiological functions. This raises the need to revise some basic assumptions concerning opsin expression, structure, classification, and evolution.

Gene expression patterns of novel visual and non-visual opsin families in immature and mature Japanese eel males [PDF]
PeerJ, 2020 This study was carried out to identify and estimate physiological function of a new type of opsin subfamily present in the retina and whole brain tissues of Japanese eel using RNA–Seq transcriptome method.

Insects, 2023 Expanding on previous efforts to survey the visual opsin repertoires of the Hemiptera, this study confirms that homologs of the UV- and LW-opsin subfamilies are conserved in all Hemiptera, while the B-opsin subfamily is missing from the Heteroptera and ...

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.
