Rhodopsin 7–The unusual Rhodopsin in Drosophila [PDF]
Rhodopsins are the major photopigments in the fruit fly Drosophila melanogaster. Drosophila express six well-characterized Rhodopsins (Rh1–Rh6) with distinct absorption maxima and expression pattern.

Deceptive beauty of non-natural structures. [PDF]
Abstract Structures of proteins and multiprotein complexes are considered landmark achievements. However, in many cases, mutant proteins are used for structural work. Even when wild type proteins are used, crystallization or complex formation for cryoEM is performed in highly nonphysiological conditions.

Accumulation of rhodopsin in late endosomes triggers photoreceptor cell degeneration. [PDF]
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

Retinitis pigmentosa: A Case Report with Thr17Arg as a Novel Mutation in RHO Gene. [PDF]
Background and Aim: Retinitis pigmentosa (RP) is the most common type of inherited progressive photoreceptor cells degeneration causing night blindness, progressive reduction of visual field, loss of retinal pigment epithelial function, and ultimately ...

Crystal structure of rhodopsin bound to arrestin by femtosecond X-ray laser. [PDF]
G-protein-coupled receptors (GPCRs) signal primarily through G proteins or arrestins. Arrestin binding to GPCRs blocks G protein interaction and redirects signalling to numerous G-protein-independent pathways.

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

Blue light regenerates functional visual pigments in mammals through a retinyl-phospholipid intermediate. [PDF]
The light absorbing chromophore in opsin visual pigments is the protonated Schiff base of 11-cis-retinaldehyde (11cRAL). Absorption of a photon isomerizes 11cRAL to all-trans-retinaldehyde (atRAL), briefly activating the pigment before it dissociates ...

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

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 ...

Gi- and Gs-coupled GPCRs show different modes of G-protein binding. [PDF]
More than two decades ago, the activation mechanism for the membrane-bound photoreceptor and prototypical G protein-coupled receptor (GPCR) rhodopsin was uncovered.
