    Semisynthetic biosensors for mapping cellular concentrations of nicotinamide adenine dinucleotides

    Olivier Sallin et al.
    A family of fluorescent biosensors for nicotinamide adenine dinucleotides allows quantification of these cofactors in live cells with spatio-temporal resolution.

    Nicotinamide adenine dinucleotide is transported into mammalian mitochondria

    Antonio Davila et al.
    Stable isotope labeling reveals that NAD crosses the inner membrane of mammalian mitochondria via an unknown transporter.

    A lectin receptor kinase as a potential sensor for extracellular nicotinamide adenine dinucleotide in Arabidopsis thaliana

    Chenggang Wang et al.
    Genetic and biochemical analyses demonstrate that cell-surface lectin receptors can potentially function as extracellular NAD+-binding receptors and provide direct evidence for extracellular NAD+ being a bona fide endogenous signaling molecule in plants.

    A vitamin-B2-sensing mechanism that regulates gut protease activity to impact animal’s food behavior and growth

    Bin Qi et al.
    The availability of an essential dietary micronutrient is evaluated by an intestinal signaling system that in turn regulates food-uptake and response behaviors by modulating protease expression.

    SIRT6 regulates Ras-related protein R-Ras2 by lysine defatty-acylation

    Xiaoyu Zhang et al.
    A posttranslational regulatory mechanism for a Ras family small GTPase could open up new directions to understand and control the Ras family of proteins that are important for physiology and diseases.

    Analysis of protein phosphorylation in nerve terminal reveals extensive changes in active zone proteins upon exocytosis

    Mahdokht Kohansal-Nodehi et al.
    Global phosphoproteomic analysis in nerve terminal during exocytosis reveals 252 uniquely regulated phosphosites, highlighting complex regulation of active zone proteins at multiple sites and the role of specific kinases/phosphatases.

    Sir2 phosphorylation through cAMP-PKA and CK2 signaling inhibits the lifespan extension activity of Sir2 in yeast

    Woo Kyu Kang et al.
    The deacetylase Sir2 fine-tunes transcription of PMA1 and other aging related genes in a cAMP-PKA and CK2 signaling dependent manner.

    Dual control of NAD+ synthesis by purine metabolites in yeast

    Benoît Pinson et al.
    Two distinct processes drive coordinated synthesis of purine and pyridine (NAD+) nucleotides in response to AICAR derivatives and ATP.

    PLZF targets developmental enhancers for activation during osteogenic differentiation of human mesenchymal stem cells

    Shuchi Agrawal Singh et al.
    A key transcription-factor for osteogenic differentiation, PLZF, acts as a transcriptional activator by binding to active developmental enhancers and facilitates mediator recruitment, but is not involved in enhancer looping.
