Ubiquitin Signaling: Extreme Conservation as a Source of Diversity
Cells, 2014 Around 2 × 103–2.5 × 103 million years ago, a unicellular organism with radically novel features, ancestor of all eukaryotes, dwelt the earth. This organism, commonly referred as the last eukaryotic common ancestor, contained in its proteome the same ...

The proteasome lid triggers COP9 signalosome activity during the transition of Saccharomyces cerevisiae cells into quiescence. [PDF]
, 2019 The class of Cullin–RING E3 ligases (CRLs) selectively ubiquitinate a large portion of proteins targeted for proteolysis by the 26S proteasome. Before degradation, ubiquitin molecules are removed from their conjugated proteins by deubiquitinating enzymes,

Advanced Science, EarlyView.Calhm6 drives M2 macrophage polarization via the Chp1‐Camk4‐Creb1 axis, suppressing inflammation through calcium‐dependent ectosomal delivery. Calhm6 deficiency enhances M1 responses, boosting bactericidal activity but exacerbating tissue damage. LPS/IFNγ upregulate Calhm6 via Irf1, while IL‐4/Stat6 inhibits it, balancing immune outcomes.

Control of DNA Replication Initiation by Ubiquitin
Cells, 2018 Eukaryotic cells divide by accomplishing a program of events in which the replication of the genome is a fundamental part. To ensure all cells have an accurate copy of the genome, DNA replication occurs only once per cell cycle and is controlled by ...

Advanced Science, EarlyView.Polyhalogenated carbazoles (PHCZ), persistent environmental contaminants, preferentially accumulate in neuronal tissues. Studies using Caenorhabditis elegans and human neuronal cell lines reveal that PHCZ induce dopaminergic neurodegeneration by promoting liquid–liquid phase separation of α‐synuclein, reducing condensate fluidity, impairing ...

Advanced Science, EarlyView.Mobile messenger RNAs (mRNAs) can travel long distances, serving as systemic signals that participate in plant growth and stress acclimation. This work determines that PHR proteins mediate the Pi starvation response (PSR)‐specific long‐distance transport of mRNAs and that these PSR‐specific mobile mRNAs represent noncoding transcripts in recipient ...

Discovery of a Potent and Selective TEAD Degrader with Durable Degradation Activity
Advanced Science, EarlyView.KG‐FP‐003, a highly potent TEAD‐YAP PROTAC derived from the patented inhibitor is developed. It selectively degrades endogenous TEAD proteins in HiBiT systems without IMiD‐related off‐target effects. Screening across 867 cancer cell lines revealed broad and superior anti‐tumor activity, highlighting its therapeutic potential through targeted TEAD ...
