Identification and Expression Patterns of Opsin Genes in a Forest Insect, Dendrolimus punctatus

open access: yesInsects, 2020
Dendrolimus punctatus walker (Lepidoptera: Lasiocampidae) is the most serious coniferous forest defoliator in China. This species has long life history, and shows different activity rhythms and light response behaviors at larval and adult stages.

Identification of a Non-Retinoid Opsin Ligand Through Pharmacophore-Guided Virtual Screening—A Novel Potential Rhodopsin-Stabilizing Compound

open access: yesMolecules
Rhodopsin, a G-protein-coupled receptor (GPCR) comprising the protein opsin covalently linked to the chromophore 11-cis retinal, is pivotal in visual phototransduction.

Color vision: Opsins and options [PDF]

open access: yesProceedings of the National Academy of Sciences, 1999
A recent estimate suggests that we can potentially distinguish 2.3 million colors (1), and yet we achieve this by comparing the rates at which photons are absorbed in just three classes of retinal photopigment (Fig. 1 Lower). The photopigments consist of 11-cis-retinal bound to different “opsins,” which are members of the large family of G-protein ...

Müller Glia Subtypes Define Neuro‐Glial Associations and Spatial Morphogen Axes in the Zebrafish Retina

open access: yesGlia, Volume 74, Issue 11, November 2026.
Zebrafish Müller glia are heterogeneous in the early larval retina. Zebrafish Müller glia subtypes define a spatial axis of retinoic acid metabolism. Neuron‐associated glial programs identified in Zebrafish Müller glia are evolutionarily conserved in mammals. ABSTRACT Müller glia are instrumental macroglia of the vertebrate retina, once thought to be a

Ten‐Eleven Translocation Enzymes Control the Rate and Mode of Retinal Progenitor Cell Division in the Developing Retina

open access: yesThe FASEB Journal, Volume 40, Issue 19, 15 October 2026.
Early RPCs divide predominantly symmetrically and exhibit a high proliferation rate, resulting in rapid retinal growth. Late RPCs divide predominantly asymmetrically and exhibit a low proliferation rate. Our results suggest that TET‐deficient RPCs divide predominantly asymmetrically but exhibit a high proliferation rate.

Duplication and Losses of Opsin Genes in Lophotrochozoan Evolution

open access: yes, 2023
Opsins are G-coupled receptors playing a key role in metazoan visual processes. While many studies enriched our understanding of opsin diversity in several animal clades, the opsin evolution in Lophotrochozoa, one of the major metazoan groups, remains ...

Engineering of an artificial light-modulated potassium channel.

open access: yesPLoS ONE, 2012
Ion Channel-Coupled Receptors (ICCRs) are artificial receptor-channel fusion proteins designed to couple ligand binding to channel gating. We previously validated the ICCR concept with various G protein-coupled receptors (GPCRs) fused with the inward ...
