Signaling in the plant cytosol: cysteine or sulfide?
(Springer, 2015)
Cysteine (Cys) is the first organic compound containing reduced sulfur that is synthesized in the last stage of plant photosynthetic assimilation of sulfate. It is a very important metabolite not only because it is crucial ...

HuR thermal stability is dependent on domain binding and upon phosphorylation
(Springer, 2012)
Human antigen R (HuR) is a multitasking RNA binding protein involved in posttranscriptional regulation by recognizing adenine- and uracile-rich elements placed at the 3′-untranslated regions of messenger RNAs (mRNAs). The ...

Photorespiration: regulation and new insights on the potential role of persulfidation
(Oxford University Press, 2023-07-24)
Photorespiration has been considered a 'futile' cycle in C3 plants, necessary to detoxify and recycle the metabolites generated by the oxygenating activity of Rubisco. However, several reports indicate that this metabolic ...

Signaling by hydrogen sulfide and cyanide through post-translational modification
(Oxford University Press, 2019)
Two cysteine metabolism-related molecules, hydrogen sulfide and hydrogen cyanide, which are considered toxic, have now been considered as signaling molecules. Hydrogen sulfide is produced in chloroplasts through the activity ...

Persulfidation is the mechanism underlying sulfide-signaling of autophagy
(Taylor & Francis, 2021)
In this commentary, we highlight the findings described in a recent paper regarding the mechanism of H2S regulation of macroautophagy/autophagy in mammalian cells and discuss the similarities/divergencies with plant cells. ...

Abscisic acid-triggered persulfidation of the cys protease ATG4 mediates regulation of autophagy by sulfide
(American Society of Plant Biologists, 2020)
Hydrogen sulfide is a signaling molecule that regulates essential processes in plants, such as autophagy. In Arabidopsis (Arabidopsis thaliana), hydrogen sulfide negatively regulates autophagy independently of reactive ...

The binding of TIA-1 to RNA C-rich sequences is driven by its C-terminal RRM domain
(Taylor & Francis, 2014)
T-cell intracellular antigen-1 (TIA-1) is a key DNA/RNA binding protein that regulates translation by sequestering target mRNAs in stress granules (SG) in response to stress conditions. TIA-1 possesses three RNA recognition ...

Hydrogen Sulfide: A Key Role in Autophagy Regulation from Plants to Mammalians
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
Autophagy is a degradative conserved process in eukaryotes to recycle unwanted cellular protein aggregates and damaged organelles. Autophagy plays an important role under normal physiological conditions in multiple biological ...

Persulfidation proteome reveals the regulation of protein function by hydrogen sulfide in diverse biological processes in Arabidopsis
(Oxford University Press, 2017)
Hydrogen sulfide-mediated signaling pathways regulate many physiological and pathophysiological processes in mammalian and plant systems. The molecular mechanism by which hydrogen sulfide exerts its action involves ...

Cysteine and cysteine-related signaling pathways in arabidopsis thaliana
(Oxford University Press, 2014)
Cysteine occupies a central position in plant metabolism because it is a reduced sulfur donor molecule involved in the synthesis of essential biomolecules and defense compounds. Moreover, cysteine per se and its derivative ...
