S-nitrosation impairs KLF4 activity and instigates endothelial dysfunction in pulmonary arterial hypertension [PDF]
Krüppel-like factor 4 (KLF4) is a transcription factor with conserved zinc finger domains. As an essential regulator of vascular homeostasis, KLF4 exerts a protective effect in endothelial cells (ECs), including regulating vasodilation, inflammation ...

ESNOQ, proteomic quantification of endogenous S-nitrosation. [PDF]
S-nitrosation is a post-translational protein modification and is one of the most important mechanisms of NO signaling. Endogenous S-nitrosothiol (SNO) quantification is a challenge for detailed functional studies.

Oxygen-linked S-nitrosation in fish myoglobins: a cysteine-specific tertiary allosteric effect. [PDF]
The discovery that cysteine (Cys) S-nitrosation of trout myoglobin (Mb) increases heme O2 affinity has revealed a novel allosteric effect that may promote hypoxia-induced nitric oxide (NO) delivery in the trout heart and improve myocardial efficiency. To

S-nitros(yl)ation of CaMKIIα and its precision redox regulation by SNOTAC plays a critical role in learning and memory [PDF]
Ca2+/calmodulin-dependent protein kinase II α (CaMKIIα) and nitric oxide (NO) both play vital roles in learning and memory; however, the underlying mechanisms connecting them have remained elusive.

S-Nitrosation of E3 Ubiquitin Ligase Complex Components Regulates Hormonal Signalings in Arabidopsis
E3 ubiquitin ligases mediate the last step of the ubiquitination pathway in the ubiquitin-proteasome system (UPS). By targeting transcriptional regulators for their turnover, E3s play a crucial role in every aspect of plant biology.

Nitric oxide destabilizes Pias3 and regulates sumoylation. [PDF]
Small ubiquitin-related protein modifiers (SUMO) modification is an important mechanism for posttranslational regulation of protein function. However, it is largely unknown how the sumoylation pathway is regulated.

NO and Heme Proteins: Cross-Talk between Heme and Cysteine Residues
Heme proteins are a diverse group that includes several unrelated families. Their biological function is mainly associated with the reactivity of the heme group, which—among several other reactions—can bind to and react with nitric oxide (NO) and other ...

Keap1 controls protein S-nitrosation and apoptosis-senescence switch in endothelial cells
Premature senescence, a death escaping pathway for cells experiencing stress, is conducive to aging and cardiovascular diseases. The molecular switch between senescent and apoptotic fate remains, however, poorly recognized.
