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

Unexpected microbial rhodopsin dynamics in sync with phytoplankton blooms

Nature Communications
The surface ocean is the largest sunlit environment on Earth where marine microalgae are known as the main drivers of global productivity. However, rhodopsin phototrophs are actually the most abundant metabolic group, suggesting a major role in the ...

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),

Diversity of Aerobic Anoxygenic Phototrophs and Rhodopsin-Containing Bacteria in the Surface Microlayer, Water Column and Epilithic Biofilms of Lake Baikal

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 ...

Rhodopsin Forms Nanodomains in Rod Outer Segment Disc Membranes of the Cold-Blooded Xenopus laevis. [PDF]

PLoS ONE, 2015
Rhodopsin forms nanoscale domains (i.e., nanodomains) in rod outer segment disc membranes from mammalian species. It is unclear whether rhodopsin arranges in a similar manner in amphibian species, which are often used as a model system to investigate the

C-terminal threonines and serines play distinct roles in the desensitization of rhodopsin, a G protein-coupled receptor

eLife, 2015
Rod photoreceptors generate measurable responses to single-photon activation of individual molecules of the G protein-coupled receptor (GPCR), rhodopsin.

Structural basis for the allosteric modulation of rhodopsin by nanobody binding to its extracellular domain

Nature Communications, 2023
Rhodopsin is a prototypical G protein-coupled receptor (GPCR) critical for vertebrate vision. Research on GPCR signaling states has been facilitated using llama-derived nanobodies (Nbs), some of which bind to the intracellular surface to allosterically ...

Rhodopsin gene expression determines rod outer segment size and rod cell resistance to a dominant-negative neurodegeneration mutant.

PLoS ONE, 2012
Two outstanding unknowns in the biology of photoreceptors are the molecular determinants of cell size, which is remarkably uniform among mammalian species, and the mechanisms of rod cell death associated with inherited neurodegenerative blinding diseases
