Rhodopsin 7–The unusual Rhodopsin inDrosophila [PDF]
PeerJ, 2016 Rhodopsins are the major photopigments in the fruit flyDrosophila melanogaster. Drosophilaexpress six well-characterized Rhodopsins (Rh1–Rh6) with distinct absorption maxima and expression pattern. In 2000, when theDrosophilagenome was published, a novelRhodopsingene was discovered:Rhodopsin 7(Rh7).Rh7is highly conserved among theDrosophilagenus and is

Rhodopsin/Lipid Hydrophobic Matching—Rhodopsin Oligomerization and Function [PDF]
Biophysical Journal, 2015 Lipid composition of the membrane and rhodopsin packing density strongly modulate the early steps of the visual response of photoreceptor membranes. In this study, lipid-order and bovine rhodopsin function in proteoliposomes composed of the sn-1 chain perdeuterated lipids 14:0d27-14:1-PC, 16:0d31-16:1-PC, 18:0d35-18:1-PC, or 20:0d39-20:1-PC at ...

Feedback from rhodopsin controls rhodopsin exclusion in Drosophila photoreceptors [PDF]
Nature, 2011 Sensory systems with high discriminatory power use neurons that express only one of several alternative sensory receptor proteins. This exclusive receptor gene expression restricts the sensitivity spectrum of neurons and is coordinated with the choice of their synaptic targets.

Structural studies on rhodopsin
Biochimica et Biophysica Acta (BBA) - Biomembranes, 2002 Bovine rhodopsin is the prototypical G protein coupled receptor (GPCR). It was the first GPCR to be obtained in quantity and studied in detail. It is also the first GPCR for which detailed three dimensional structural information has been obtained. Reviewed here are the experiments leading up to the high resolution structure determination of rhodopsin ...

Untersuchungen zur Phosphorylierung von Rhodopsin und deren Einfluss auf die Arrestin-Rhodopsin-Bindung [PDF]
, 2021 Die phosphorylierungsabhängige Bindung von Arrestin an G-Protein-gekoppelte Rezeptoren (GPCRs) ist ein weit verbreiteter Mechanismus, um aktive Rezeptoren zu inhibieren. Für die Bindung von Arrestin an lichtaktiviertes, phosphoryliertes Rhodopsin (pRho),

Photoisomerization detected in a fully wavelength-tunable rhodopsin mimic system. [PDF]
Acta Crystallogr D Struct BiolThe mechanism of retinal photoswitching is illuminated in a designed rhodopsin mimic. Two mechanisms, a conventional cis–trans isomerization and an unprecedented `photodehydration', are observed at atomic resolution in single crystals.We describe the photoisomerization of the retinylidene protonated Schiff base in human retinol‐binding protein II ...

Violet light down-regulates the expression of specific differentiation markers through Rhodopsin in normal human epidermal keratinocytes. [PDF]
PLoS ONE, 2013 Several recent reports have demonstrated that photoreceptors are expressed in human skin. The rod and cone photoreceptor-like proteins are expressed in human skin and rhodopsin, long wavelength-opsin, and short wavelength-opsin are also present in ...

Accumulation of rhodopsin in late endosomes triggers photoreceptor cell degeneration. [PDF]
PLoS Genetics, 2009 Progressive retinal degeneration is the underlying feature of many human retinal dystrophies. Previous work using Drosophila as a model system and analysis of specific mutations in human rhodopsin have uncovered a connection between rhodopsin endocytosis

PLoS ONE, 2011 BackgroundP23H rhodopsin, a mutant rhodopsin, is known to aggregate and cause retinal degeneration. However, its effects on retinal pigment epithelial (RPE) cells are unknown. The purpose of this study was to determine the effect of P23H rhodopsin in RPE

Microorganisms, 2021 The diversity of aerobic anoxygenic phototrophs (AAPs) and rhodopsin-containing bacteria in the surface microlayer, water column, and epilithic biofilms of Lake Baikal was studied for the first time, employing pufM and rhodopsin genes, and compared to ...
