Transcriptional Feedback Loops in the Caprine Circadian Clock System

open access: yesFrontiers in Veterinary Science, 2022
The circadian clock system is based on interlocked positive and negative transcriptional and translational feedback loops of core clock genes and their encoded proteins.

Characterizing the circadian connectome of Ocimum tenuiflorum using an integrated network theoretic framework

open access: yesScientific Reports, 2023
Across the three domains of life, circadian clock is known to regulate vital physiological processes, like, growth, development, defence etc. by anticipating environmental cues.

SnapShot: Circadian Clock Proteins

open access: yesCell, 2008
The earth’s rotation about its axis generates predictable changes in light and temperature, which define the 24 hr day-night cycle. Organisms from bacteria to humans have evolved an internal timekeeper to anticipate these environmental changes. This timekeeper—the circadian clock—allows organisms to parse biological processes to the appropriate time of

Diel pattern of circadian clock and storage protein gene expression in leaves and during seed filling in cowpea (Vigna unguiculata) [PDF]

open access: yes, 2018
Background Cowpea (Vigna unguiculata) is an important source of protein supply for animal and human nutrition. The major storage globulins VICILIN and LEGUMIN (LEG) are synthesized from several genes including LEGA, LEGB, LEGJ and CVC (CONVICILIN).

Stabilizing daily clock proteins [PDF]

open access: yesBiochemical Journal, 2006
Biological timekeeping is determined by internal temporal programmes and the resetting of these programmes or clocks by external stimuli. Many of the core genes of the mammalian daily or circadian clock are known, but the factors regulating so-called ‘clock’ gene proteins are unclear.

Interaction of circadian clock proteins PER2 and CRY with BMAL1 and CLOCK [PDF]

open access: yesBMC Molecular Biology, 2008
Circadian oscillation of clock-controlled gene expression is mainly regulated at the transcriptional level. Heterodimers of CLOCK and BMAL1 act as activators of target gene transcription; however, interactions of PER and CRY proteins with the heterodimer abolish its transcriptional activation capacity.

The genetic equidistance result of molecular evolution is independent of mutation rates [PDF]

open access: yes, 2008
The well-established genetic equidistance result shows that sister species are approximately equidistant to a simpler outgroup as measured by DNA or protein dissimilarity.

Low-Light Dependence of the Magnetic Field Effect on Cryptochromes: Possible Relevance to Plant Ecology

open access: yesFrontiers in Plant Science, 2018
Various responses to static magnetic fields (MF) have been reported in plants, and it has been suggested that the geomagnetic field influences plant physiology. Accordingly, diverse mechanisms have been proposed to mediate MF effects in plants.

Recent advances in modulators of circadian rhythms: an update and perspective

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2020
Circadian rhythm is a universal life phenomenon that plays an important role in maintaining the multiple physiological functions and regulating the adaptability to internal and external environments of flora and fauna.

Circadian clock proteins regulate neuronal redox homeostasis and neurodegeneration [PDF]

open access: yes, 2013
Brain aging is associated with diminished circadian clock output and decreased expression of the core clock proteins, which regulate many aspects of cellular biochemistry and metabolism.
