Advanced Science, EarlyView.G4‐binding proteins (G4BPs) that specifically co‐bind G4s in the presence of small‐molecule ligands represent a critical but unexplored class of proteins. We introduce G4‐Ligand‐Directed PROTACs (G4L‐TACs), a chemical platform that couples G4 ligands (PDS) to E3 recruiters to selectively degrade these ligand‐co‐binding G4BPs.

Caspase-mediated DDX46 cleavage unchains antiviral immunity
mBioDEAD/H-box RNA helicases are critical regulators of host antiviral innate immunity. In this study, we utilized an RNA-binding protein knockout sub-library to identify DDX46, a member of the DEAD/H-box RNA helicase family, as an essential proviral host ...

RNA helicases mediate structural transitions and compositional changes in pre-ribosomal complexes
Nature Communications, 2018 Production of eukaryotic ribosomal subunits is a highly dynamic process; pre-ribosomes undergo numerous structural rearrangements that establish the architecture present in mature complexes and serve as key checkpoints, ensuring the fidelity of ribosome ...

Processing of G4 DNA by Dna2 Helicase/nuclease and RPA provides insights into the mechanism of Dna2/RPA substrate recognition [PDF]
, 2008 The polyguanine-rich DNA sequences commonly found at telomeres and in rDNA arrays have been shown to assemble into structures known as G quadruplexes, or G4 DNA, stabilized by base-stacked G quartets, an arrangement of four hydrogen-bonded guanines.

RNA helicases and remodeling proteins
Current Opinion in Chemical Biology, 2011 It is becoming increasingly clear that RNA molecules play a major role in all aspects of metabolism. The conformational state and stability of RNA are controlled by RNA remodeling proteins, which are ubiquitous motor proteins in the cell. Here, we review advances in our understanding of the structure and function of three major structural families of ...

Advanced Science, EarlyView.SETD1A is a key epigenetic regulator in NPCs during IDD. In normal NPCs, it sustains H3K4me3–HELZ2/PPARα–HIF1α signaling to maintain glycolytic energy metabolism and proliferation. In degenerated NPCs, reduced SETD1A disrupts this axis, impairing glycolysis and accelerating senescence, highlighting a promising therapeutic target for IDD.

Accelerated epigenetic aging in Werner syndrome. [PDF]
, 2017 Individuals suffering from Werner syndrome (WS) exhibit many clinical signs of accelerated aging. While the underlying constitutional mutation leads to accelerated rates of DNA damage, it is not yet known whether WS is also associated with an increased ...

Sensing and Filtering Environmental Fluctuations: The Case of Biomolecular Condensates in Plants
Advanced Science, EarlyView.The diversity of plant condensates reflects constraints of sessile organisms to coordinate postembryonic development with environmental adaptation. This review examines how plants employ condensates to integrate temperature, light, redox, and nutrient signals.
