Aggregate, 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 ...

Analogies between halorhodopsin and bacteriorhodopsin [PDF]
, 2000 The light-activated proton-pumping bacteriorhodopsin and chloride ion-pumping halorhodopsin are compared. They belong to the family of retinal proteins, with 25% amino acid sequence homology.

Chromophore equilibria in bacteriorhodopsin
Biophysical Journal, 1979 An investigation of the dark equilibria between different chromophores of bacteriorhodopsin (BR) and studies of the kinetics of their interconversion and photochemical activity have led to the following conclusions. (a) A component of the 605-nm chromophore of BR decays in the millisecond range and is likely to be identical to the intermediate O of the

Ion Transport of Biohybrid Asymmetric Membranes by pH and Light‐Cooperative Modulation
Advanced Materials Interfaces, 2020 Bacteriorhodopsin (bR) is an excellent light‐driven proton pump and plays a vital role in chemical and biological analytical processes, such as maintaining osmotic balance, intracellular acidity, and participating in photosynthesis.

Cryo-EM structures of the channelrhodopsin ChRmine in lipid nanodiscs
Nature Communications, 2022 ChRmine is a bacteriorhodopsin-like cation channelrhodopsin (BCCR). Here, the authors present cryo-EM structures of ChRmine in apo- and retinal-bound forms to provide insight into channel activity in a BCCR and facilitate engineering of ChRmine-based ...

Photoisomerization detected in a fully wavelength‐tunable rhodopsin mimic system
Acta Crystallographica Section D, Volume 82, Issue 6, Page 664-671, June 2026.The mechanism of retinal photoswitching is illuminated in a designed rhodopsin mimic. Two mechanisms, a conventional cis–trans isomerization and an unprecedented `photodehydration', are observed at atomic resolution in single crystals.We describe the photoisomerization of the retinylidene protonated Schiff base in human retinol‐binding protein II ...

Analyses and proofs of multiexponential process of bacteriorhodopsin photoelectric response
, 2001 A bacteriorhodopsin (bR)-based photodetector is prepared with the structure of stainless steel slide/bR film/aqueous electrolyte gel/copper electrode. The photoelectric response signal to a 10 ns laser pulse is measured.

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