Extremely happy to see this wonderful story out! 🔬

Here, we describe how Ki-67 anchors chromatin to nucleoli, leading them to acquire irregular shapes!!! 🫧🧬

This great story was led by Daja Schichler & Yuki Hayashi from the Cuylen Lab @embl.org

Why do nucleoli adopt irregular shapes despite their liquid-like nature?
Sara Cuylen-Häring and colleagues find that Ki-67 mediates this irregularity by tethering chromatin at the surface and creating internal chromatin invaginations

You asked, we listened. Millions of AI-predicted protein complex structures are now available in the #AlphaFold Database.

This spans homodimers from 20 of the most studied species, including humans, as well as the World Health Organization’s priority pathogens list.

High-content screening of organoids reveals the mechanisms of human pancreas acinar specification Keshara et al. conducted a high-content screen on pancreas organoids that identified 54 compounds affecting differentiation or morphogenesis. After validating 11 compounds, they focus on Gsk3A/B inhibitors, which, combined with FGF withdrawal, drive acinar cell differentiation, enabling future studies on these cells and their role in cancer initiation in humans.

Short linear motifs - Unexplored players driving Toxoplasma gondii infection Pathogens infect hosts by interacting with host proteins and exploiting their functions to their advantage. Short linear motifs, small functional regions within intrinsically disordered protein regions, are common mediators of host-pathogen protein interactions. While motifs have been more extensively studied in viruses and bacteria, the extent to which eukaryotic unicellular parasites use motifs during infection remains unexplored. Toxoplasma gondii is a widespread intracellular Apicomplexan parasite capable of infecting all warm-blooded animals and invading any of their nucleated cells. Toxoplasma's secreted proteins are key in interacting with host proteins during infection, making them potential sources for motifs. To highlight the role of motifs in Toxoplasma gondii infection, we curated 20 known motif instances in Toxoplasma proteins from the scientific literature. To identify more motifs in Toxoplasma secreted proteins, we developed a computational pipeline that annotates putative motif matches with structural and functional features. Through this approach, we identified a set of 27,832 motif matches in 296 secreted proteins. We highlight strategies for further prioritisation of likely functional motif matches by focusing on integrin motifs, degrons and TRAF6-binding motifs. We subjected four predicted TRAF6-binding motifs to experimental validation, supporting the predicted motifs in the Toxoplasma proteins RON10 and GRA15. Our motif predictions provide a valuable resource for generating hypotheses and designing experiments to study infection mechanisms. The characterisation of motifs in Toxoplasma will be key to understanding the molecular principles underlying its broad host range and more comprehensive Apicomplexan infection strategies. ### Competing Interest Statement The authors have declared no competing interest. Deutsche Forschungsgemeinschaft, 449991970

New preprint! Here, we highlight the role of motifs during the Toxoplasma host cell invasion, predict thousands of motifs in its effector proteins, and validate the binding of TRAF6 motifs. Our results are intended to catalyse further research on motifs and parasites.

Toxoplasma effector TgROP1 establishes membrane contact sites with the endoplasmic reticulum during infection - Nature Microbiology The Toxoplasma gondii effector TgROP1 mimics host factors to bind VAPA/B, thereby establishing parasite–host ER contact sites.

During host cell invasion, Toxoplasma mimics the FFAT motif and repurposes it to associate its parasitophorous vacuole to the endoplasmic reticulum!
