Far-Red Absorbing Rhodopsins, Insights From Heterodimeric Rhodopsin-Cyclases

open access: yesFrontiers in Molecular Biosciences, 2022
The recently discovered Rhodopsin-cyclases from Chytridiomycota fungi show completely unexpected properties for microbial rhodopsins. These photoreceptors function exclusively as heterodimers, with the two subunits that have very different retinal ...

Ion-pumping microbial rhodopsin protein classification by machine learning approach

open access: yesBMC Bioinformatics, 2023
Background Rhodopsin is a seven-transmembrane protein covalently linked with retinal chromophore that absorbs photons for energy conversion and intracellular signaling in eukaryotes, bacteria, and archaea.

Reverse optogenetics of G protein signaling by zebrafish non-visual opsin Opn7b for synchronization of neuronal networks

open access: yesNature Communications, 2021
Microbial rhodopsins can be used to control action potentials, while animal opsins can be used to control intracellular signaling pathways. The authors identify Opn7b as constitutively active Gi/o coupled receptor that can be deactivated by light and ...

Viral rhodopsins 1 are an unique family of light-gated cation channels

open access: yesNature Communications, 2020
Nucleocytoplasmic Large DNA Viruses (NCLDV) that infect algae encode two distinct families of microbial rhodopsins. Here, the authors characterise two proteins form the viral rhodopsin group 1 OLPVR1 and VirChR1, present the 1.4 Å crystal structure of ...

Voltage imaging with engineered proton-pumping Rhodopsins: Insights from the proton transfer pathway [PDF]

open access: yes, 2023
Voltage imaging using genetically encoded voltage indicators (GEVI) has taken the field of neuroscience by storm in the past decade. Its ability to create subcellular and network level readouts of electrical dynamics depends critically on the kinetics of

Flotillin-associated rhodopsin (FArhodopsin), a widespread paralog of proteorhodopsin in aquatic bacteria with streamlined genomes

open access: yesmSystems, 2023
Microbial rhodopsins are found more than once in a single genome (paralogs) often have different functions. We screened a large dataset of open ocean single-amplified genomes (SAGs) for co-occurrences of multiple rhodopsin genes.
