Blue-light induced accumulation of reactive oxygen species is a consequence of the Drosophila cryptochrome photocycle. [PDF]
PLoS ONE, 2017 Cryptochromes are evolutionarily conserved blue-light absorbing flavoproteins which participate in many important cellular processes including in entrainment of the circadian clock in plants, Drosophila and humans.

Kinetics of the LOV domain of ZEITLUPE determine its circadian function in Arabidopsis
eLife, 2017 A LOV (Light, Oxygen, or Voltage) domain containing blue-light photoreceptor ZEITLUPE (ZTL) directs circadian timing by degrading clock proteins in plants. Functions hinge upon allosteric differences coupled to the ZTL photocycle; however, structural and

Biophysical characterization of microbial rhodopsins with DSE motif
Biophysics and Physicobiology, 2023 Microbial rhodopsins are photoreceptive transmembrane proteins that transport ions or regulate other intracellular biological processes. Recent genomic and metagenomic analyses found many microbial rhodopsins with unique sequences distinct from known ...

Incoherent manipulation of the photoactive yellow protein photocycle with dispersed pump-dump-probe spectroscopy. [PDF]
, 2004 Photoactive yellow protein is the protein responsible for initiating the “blue-light vision” of Halorhodospira halophila. The dynamical processes responsible for triggering the photoactive yellow protein photocycle have been disentangled with the use of ...

Molecular Dynamics of Channelrhodopsin at the Early Stages of Channel Opening. [PDF]
PLoS ONE, 2015 Channelrhodopsin (ChR) is a light-gated cation channel that responds to blue light. Since ChR can be readily expressed in specific neurons to precisely control their activities by light, it has become a powerful tool in neuroscience.

RUP2 facilitates UVR8 redimerization via two interfaces
Plant Communications, 2023 The plant UV-B photoreceptor UV RESISTANCE LOCUS 8 (UVR8) exists as a homodimer in its inactive ground state. Upon UV-B exposure, UVR8 monomerizes and interacts with a downstream key regulator, the CONSTITUTIVE PHOTOMORPHOGENIC 1/SUPPRESSOR OF PHYA (COP1/
