Circadian Rhythm Abnormalities in Parkinson's Disease from Humans to Flies and Back [PDF]
, 2018 Clinical and research studies have suggested a link between Parkinson\u2019s disease (PD) and alterations in the circadian clock. Drosophila melanogaster may represent a useful model to study the relationship between the circadian clock and PD.

ZINC-FINGER interactions mediate transcriptional regulation of hypocotyl growth in Arabidopsis [PDF]
, 2018 Integration of environmental signals and interactions among photoreceptors and transcriptional regulators is key in shaping plant development. TANDEM ZINC-FINGER PLUS3 (TZP) is an integrator of light and photoperiodic signaling that promotes flowering in

Action Spectrum of Drosophila Cryptochrome [PDF]
Journal of Biological Chemistry, 2007 Cryptochromes are a highly conserved class of UV-A/blue light photoreceptors. In Drosophila, cryptochrome is required for the normal entrainment of circadian rhythms to light dark cycles. The photocycle and molecular mechanism of animal cryptochrome photoreception are presently unknown. Drosophila cryptochrome undergoes light-dependent degradation when

Vertebrate Cryptochromes are Vestigial Flavoproteins [PDF]
Scientific Reports, 2017 AbstractAll cryptochromes are currently classified as flavoproteins. In animals their best-described role is as components of the circadian clock. This circadian function is variable, and can be either light-dependent or -independent; the molecular origin of this difference is unknown.

Circadian rhythms and hormonal homeostasis: Pathophysiological implications [PDF]
, 2017 Over recent years, a deeper comprehension of the molecular mechanisms that control biological clocks and circadian rhythms has been achieved. In fact, many studies have contributed to unravelling the importance of the molecular clock for the regulation ...

Genome biology, 2005 Cryptochromes are photoreceptors that regulate entrainment by light of the circadian clock in plants and animals. They also act as integral parts of the central circadian oscillator in animal brains and as receptors controlling photomorphogenesis in response to blue or ultraviolet (UV-A) light in plants.

One Actor, Multiple Roles: The Performances of Cryptochrome in Drosophila
Frontiers in Physiology, 2020 Cryptochromes (CRYs) are flavoproteins that are sensitive to blue light, first identified in Arabidopsis and then in Drosophila and mice. They are evolutionarily conserved and play fundamental roles in the circadian clock of living organisms, enabling ...
