Histone H2A variants alpha1-extension helix directs RNF168-mediated ubiquitination
13hNature Communications, Published online: 18 May 2020; doi:10.1038/s41467-020-16307-4 Histone ubiquitination plays a critical role in the DNA damage response pathway. Here the authors reveal how RNF168 ubiquitinates the H2A family including noncanonical variants, H2AZ and macroH2A1/2, at the divergent N-terminal tail lysine residue.
Sphingolipids produced by gut bacteria enter host metabolic pathways impacting ceramide levels
13hNature Communications, Published online: 18 May 2020; doi:10.1038/s41467-020-16274-w Ceramides are a type of sphingolipid (SL) that have been shown to play a role in several metabolic disorders. Here, the authors investigate the effect of SL-production by gut Bacteroides on host SL homeostasis and show that microbiome-derived SLs enter host circulation and alter ceramide production.

13hNature Communications, Published online: 18 May 2020; doi:10.1038/s41467-020-16300-x The Transcription Factor EB (TFEB) is known to regulate cellular homeostasis and energy metabolism, but its role in cell fate determination in the liver is unknown. Here, the authors show that TFEB regulates the progenitor/cholangiocyte lineage and that its depletion prevents tissue recovery upon injury.
