Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Structure of human RNA polymerase III

Nature Communications, 2020
The eukaryotic RNA Polymerase III transcribes tRNAs, some ribosomal and spliceosomal RNAs. Here, the authors resolve a cryo-EM structure of human RNA Polymerase III in its apo form and complemented it with crystal structures and SAXS analysis of RPC5 ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Structure of an Archaeal RNA Polymerase [PDF]

Journal of Molecular Biology, 2008
Related multisubunit RNA polymerases (RNAPs) carry out gene transcription in all kingdoms of life. Since structural information is limited to bacterial and eukaryotic RNAPs, we determined the cryo-electron microscopic structure of the RNAP from the thermophilic archaeon Pyrococcus furiosus at 13 A resolution.

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Structural Biology of Bacterial RNA Polymerase

Biomolecules, 2015
Since its discovery and characterization in the early 1960s (Hurwitz, J. The discovery of RNA polymerase. J. Biol. Chem. 2005, 280, 42477–42485), an enormous amount of biochemical, biophysical and genetic data has been collected on bacterial RNA ...

Analysis of Template Variations on RNA Synthesis by Respiratory Syncytial Virus Polymerase

Viruses, 2022
Respiratory syncytial virus (RSV) is a significant threat to infants and elderly individuals globally. Currently, there are no effective therapies or treatments for RSV infection because of an insufficient understanding of the RSV viral machinery.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.
