Structure of the measles virus ternary polymerase complex

Nature Communications
Measles virus (MeV) is a highly contagious pathogen that causes significant morbidity worldwide. Its polymerase machinery, composed of the large protein (L) and phosphoprotein (P), is crucial for viral replication and transcription, making it a promising

Single-molecule tracking in live cells reveals distinct target-search strategies of transcription factors in the nucleus

eLife, 2014
Gene regulation relies on transcription factors (TFs) exploring the nucleus searching their targets. So far, most studies have focused on how fast TFs diffuse, underestimating the role of nuclear architecture.

Dynamic partitioning of a critical elongation factor between LEC and SEC regulates cellular snRNA and proliferation-related mRNA transcription

Nature Communications
Human RNA polymerase II (Pol II) regulates transcription of significant number of snRNA and proliferation-related mRNA genes by involving Little Elongation Complex (LEC) and Super Elongation Complex (SEC) respectively.

Fetal Muse-based therapy prevents lethal radio-induced gastrointestinal syndrome by intestinal regeneration

Stem Cell Research & Therapy, 2023
Background Human multilineage-differentiating stress enduring (Muse) cells are nontumorigenic endogenous pluripotent-like stem cells that can be easily obtained from various adult or fetal tissues.

Structure of the Nipah virus polymerase phosphoprotein complex

Nature Communications
The Nipah virus (NiV), a member of the Paramyxoviridae family, is notorious for its high fatality rate in humans. The RNA polymerase machinery of NiV, comprising the large protein L and the phosphoprotein P, is essential for viral replication. This study

Mutant and Wild-Type Tumor Suppressor p53 Induces p300 Autoacetylation

iScience, 2018
Summary: The transcriptional co-activator p300 is essential for p53 transactivation, although its precise role remains unclear. We report that p53 activates the acetyltransferase activity of p300 through the enhancement of p300 autoacetylation ...

ARTD10/PARP10 Induces ADP-Ribosylation of GAPDH and Recruits GAPDH into Cytosolic Membrane-Free Cell Bodies When Overexpressed in Mammalian Cells

Challenges, 2018
Protein ADP-ribosylation is a reversible post-translational modification of cellular proteins that is catalysed by enzymes that transfer one (mono) or several (poly) units of ADP-ribose from β-NAD+ to a specific amino acid of the target protein. The
