Wave Mechanics of Ciliary Proteins: Quantum‐Enabled Sensing and Energy Transfer in the “Cellular Antenna”

open access: yesAggregate, Volume 7, Issue 6, June 2026.
This review surveys eukaryotic cilia as putative quantum‐enabled sensory and regulatory centers. It highlights their multifaceted roles in the cell, focuses on the nontrivial roles of quantum mechanics in their membrane and cytoskeletal proteins, and introduces the essential building blocks enabling quantum properties to survive in the warm, wet, and ...

Light-scattering changes in the bacteriorhodopsin photocycle [PDF]

open access: yes, 1989
Light-scattering changes were found to accompany the bacteriorhodopsin photocycle in a suspension of purple membranes. A light-scattering signal comprises three phases, connected with (i) bR → M transition, (ii) transition of M to P intermediate (other ...

Hybrid retinoid analogs as instruments for the nanobiophotonic researches

open access: yesТонкие химические технологии, 2011
This mini-review presents experimental data obtained by the authors in the context of a cycle of structural-functional research on bionanophotochrome bacteriorhodopsin carried out during the past 10 years.

Direct and Label-Free Determination of Human Glycated Hemoglobin Levels Using Bacteriorhodopsin as the Biosensor Transducer

open access: yesSensors, 2020
Glycated hemoglobin (HbA1c) levels are an important index for the diagnosis and long-term control of diabetes. This study is the first to use a direct and label-free photoelectric biosensor to determine HbA1c using bacteriorhodopsin-embedded purple ...

Detailed analysis of distorted retinal and its interaction with surrounding residues in the K intermediate of bacteriorhodopsin

open access: yesCommunications Biology, 2023
Crystal structures and quantum mechanical calculations reveal the interaction and photoisomerized conformation of the retinal chromophore in the K intermediate of bacteriorhodopsin (bR), giving insights into light-driven bR proton pumping.

Bacteriorhodopsin Folds through a Poorly Organized Transition State [PDF]

open access: yes, 2014
The folding mechanisms of helical membrane proteins remain largely uncharted. Here we characterize the kinetics of bacteriorhodopsin folding and employ φ-value analysis to explore the folding transition state.

GRKs and arrestins: Nomenclature and functions in GPCR‐dependent and ‐independent signalling

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 11, Page 2619-2633, June 2026.
G protein‐coupled receptor (GPCR) kinases (GRKs) and arrestins play a critical role in the regulation of GPCR signalling. Historic names of mammalian GRKs were replaced by systematic ones in the 1990s; however, both kinds of names are currently in use for mammalian arrestins.

Opsins are phospholipid scramblases in all domains of life

open access: yesmBio
Opsins are highly abundant retinal proteins in the membranes of photoheterotrophic bacteria. However, some microbial genomes encode an opsin but lack the gene for the final enzyme in retinal synthesis.
