The Rhodopsin-Arrestin-1 Interaction in Bicelles

open access: yes, 2015
G-protein-coupled receptors (GPCRs) are essential mediators of information transfer in eukaryotic cells. Interactions between GPCRs and their binding partners modulate the signaling process. For example, the interaction between GPCR and cognate G protein

Lateral hypothalamic melanin concentrating hormone‐expressing neurons both promote and are required for cue‐potentiated feeding

open access: yesJournal of Neuroendocrinology, Volume 38, Issue 6, June 2026.
Abstract Food‐related stimuli can promote feeding behaviors independent of metabolic need. Cue‐potentiated feeding (CPF) studies in rodents offer the potential to reveal the psychobiological mechanisms underlying learned overeating behaviors. We examined whether lateral hypothalamic area (LHA) cells expressing the feeding signal Melanin Concentrating ...

N-Linked glycosylation of Drosophila rhodopsin occurs exclusively in the amino-terminal domain and functions in rhodopsin maturation

open access: yes, 1998
Immature Drosophila rhodopsin is N-glycosylated, but undergoes complete deglycosylation during the process of protein maturation. In order to elucidate the site of glycosylation and its role in rhodopsin synthesis, we investigated the in vitro and in ...

Widespread Variation in Retinochrome Spectral Absorbance Across Scallop Phylogeny

open access: yesMolecular Ecology, Volume 35, Issue 11, June 2026.
ABSTRACT Vision is a two‐step process, including phototransduction initiated by a retinal‐bound opsin photopigment, and subsequent photopigment regeneration wherein the inactive state is restored. Because retinal isomerization, or changing of the molecular structural conformation, drives the activation of opsin photopigments, the reverse process is a ...

The Elusive Fraction of Marine Plankton Diversity: Size, Abundance and Taxonomic Composition of 0.2 μm‐Filterable Prokaryotes Across Three Contrasting Coastal Environments

open access: yesMolecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT The existence of prokaryotes escaping filtration through 0.2‐μm filters has been known for decades. Such ‘filterable’ prokaryotes (hereafter ‘FP’) might include true ultra‐small groups (i.e., ultramicrobacteria), but also cells that miniaturize temporally as a physiological strategy to persist under unfavourable conditions, representing a ...

Beyond red/far‐red sensing: phytochrome perception of the marine light field by microalgae

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2837-2844, June 2026.
Summary Phytochromes (PHYs) are a major group of photoreceptors, described as red and far‐red light sensors in land plants. Recent genomic and metagenomic explorations have revealed the presence of PHYs also in various eukaryotic microalgae originating from distinct endosymbiotic events.

PBN and certain PBNDs inhibited rhodopsin regeneration.

open access: yes, 2016
Rats were treated with either PBN or certain PBNDs before 2h of light adaptation followed by 2.5h of dark adaptation after which the animals were euthanized and retinas harvested for rhodopsin assay.
