Protein-Protein Interaction Changes in an Archaeal Light-Signal Transduction [PDF]

Journal of Biomedicine and Biotechnology, 2010
Negative phototaxis inNatronomonas pharaonisis initiated by transient interaction changes between photoreceptor and transducer.pharaonisphoborhodopsin (ppR; also calledpharaonissensory rhodopsin II,psR-II) and the cognate transducer protein,pHtrII, form a tight 2 : 2 complex in the unphotolyzed state, and the interaction is somehow altered during the ...

Dynamic Genome-Wide Transcription Profiling and Direct Target Genes of CmWC-1 Reveal Hierarchical Light Signal Transduction in Cordyceps militaris

Journal of Fungi, 2022
Light is necessary for primordium differentiation and fruiting body development for most edible fungi; however, light perception and signal transduction have only been well studied in model fungi.

Microenvironment Dependent Photobiomodulation on Function-Specific Signal Transduction Pathways [PDF]

International Journal of Photoenergy, 2014
Cellular photobiomodulation on a cellular function has been shown to be homeostatic. Its function-specific pathway mechanism would be further discussed in this paper. The signal transduction pathways maintaining a normal function in its function-specific

LOV-Based Optogenetic Devices: Light-Driven Modules to Impart Photoregulated Control of Cellular Signaling

Frontiers in Molecular Biosciences, 2015
The Light-Oxygen-Voltage domain family of proteins is widespread in biology where they impart sensory responses to signal transduction domains. The small, light responsive LOV modules offer a novel platform for the construction of optogenetic tools ...

Signaling Mechanisms by Arabidopsis Cryptochromes

Frontiers in Plant Science, 2022
Cryptochromes (CRYs) are blue light photoreceptors that regulate growth, development, and metabolism in plants. In Arabidopsis thaliana (Arabidopsis), CRY1 and CRY2 possess partially redundant and overlapping functions.

An integrative model for phytochrome B mediated photomorphogenesis:from protein dynamics to physiology [PDF]

, 2010
Plants have evolved various sophisticated mechanisms to respond and adapt to changes of abiotic factors in their natural environment. Light is one of the most important abiotic environmental factors and it regulates plant growth and development ...

Phytochrome-Interacting Proteins

Biomolecules, 2023
Phytochromes are photoreceptors of plants, fungi, slime molds bacteria and heterokonts. These biliproteins sense red and far-red light and undergo light-induced changes between the two spectral forms, Pr and Pfr.

Transduction of Blue-Light Signals [PDF]

Plant Physiology, 1993
BUT IS IT AN ELEPHANT? In the old tale, several blind men are taken to an elephant. In turn, each is asked to examine and identify the mystery object. One blind man examines a leg and claims it to be a tree, another, examining the trunk, claims it to be a snake, and yet another, feeling a tusk, claims it to be a smooth rock. The pattern continues: each

FHY3 and FAR1 Act Downstream of Light Stable Phytochromes

Frontiers in Plant Science, 2016
FHY3 and FAR1 are positively-acting transcription factors that directly regulate expression of a number of target genes in Arabidopsis thaliana. Here, we looked at the regulation of one specific target gene, ELF4.
