Upon nutritional stress, several signaling pathways cooperate to change the transcription program through chromatin regulation to rewire cellular metabolism. In budding yeast, histone H3 threonine 11 phosphorylation (H3pT11) acts as a marker of low glucose stress and regulates the transcription of nutritional stress responsive genes. Understanding how this histone modification ‘senses’ external glucose changes remains elusive. Here, we show that Tda1, the yeast orthologue of human Nuak1, is a direct kinase for H3pT11 upon low glucose stress. Yeast AMPK directly phosphorylates Tda1 to govern Tda1 activity, while CK2 regulates Tda1 nuclear localization. Collectively, AMPK and CK2 signaling converge on histone kinase Tda1 to link external low glucose stress to chromatin regulation.Competing Interest StatementThe authors have declared no competing interest.
