Comparison of the molecular properties of retinitis pigmentosa P23H and N15S amino acid replacements in rhodopsin.

PLoS ONE, 2019
Mutations in the RHO gene encoding for the visual pigment protein, rhodopsin, are among the most common cause of autosomal dominant retinitis pigmentosa (ADRP).

Membrane Protein Activity Induces Specific Molecular Changes in Nanodiscs Monitored by FTIR Difference Spectroscopy

Frontiers in Molecular Biosciences, 2022
It is well known that lipids neighboring integral membrane proteins directly influence their function. The opposite effect is true as well, as membrane proteins undergo structural changes after activation and thus perturb the lipidic environment.

The cellular fate of mutant rhodopsin: quality control, degradation and aggresome formation [PDF]

, 2002
Mutations in the photopigment rhodopsin are the major cause of autosomal dominant retinitis pigmentosa. The majority of mutations in rhodopsin lead to misfolding of the protein.

New spectral templates for rhodopsin and porphyropsin visual pigments [PDF]

Archives of Biological Sciences, 2019
A four-parameter model of spectral sensitivity curves was developed. Empirical equations were designed for A1- and A2-based visual pigments with the main α-band maximum absorptions (λmax) from 350 nm, near the ultraviolet, up to 635 nm in the far-red ...

Age-related deterioration of rod vision in mice [PDF]

, 2010
Even in healthy individuals, aging leads to deterioration in visual acuity, contrast sensitivity, visual field, and dark adaptation. Little is known about the neural mechanisms that drive the age-related changes of the retina and, more specifically ...

Nano‐Gs‐Protein Peptidomimetika: Rationales Design von Peptiden, die vom C‐Terminus von Gα abgeleitet sind und Schlüsselkomponenten der Gs‐β2AR‐Wechselwirkungen nachahmen

Angewandte Chemie, EarlyView.
G Protein‐gekoppelte Rezeptoren (GPCRs) sind wichtige therapeutische Zielstrukturen. Die Modulation der GPCR‐Aktivität über intrazelluläre Bindungsstellen gewinnt zunehmend an Bedeutung. Ein strukturell und computergestützter Ansatz ermöglichte die Entwicklung kleiner, vom G Protein abgeleiteter Peptidomimetika, die gezielt an die intrazelluläre ...

A Y178C rhodopsin mutation causes aggregation and comparatively severe retinal degeneration

Cell Death Discovery
Rhodopsin is the light-activated G protein-coupled receptor that initiates vision in photoreceptor cells of the retina. Numerous mutations in rhodopsin promote receptor misfolding and aggregation, causing autosomal dominant retinitis pigmentosa, a ...

Functional Expression of Gloeobacter Rhodopsin in PSI-Less Synechocystis sp. PCC6803

Frontiers in Bioengineering and Biotechnology, 2019
The approach of providing an oxygenic photosynthetic organism with a cyclic electron transfer system, i.e., a far-red light-driven proton pump, is widely proposed to maximize photosynthetic efficiency via expanding the absorption spectrum of ...
