Study today in @natcellbio.nature.com by @mathilda95.bsky.social @nadlerlab.bsky.social @mpi-cbg.de, Honigmann group @biotec-tud.bsky.social & @carldmodes.bsky.social reveals that clathrin-mediated endocytosis sorts proteins but not lipids. Lipids use different routes. www.mpi-cbg.de/news-outreac...

A conserved motif tunes Sidekick condensate dynamics to control tricellular junction recruitment during epithelial remodeling
Spatial regulation of cell adhesion molecules in tissue dynamics underpins morphogenesis. Uechi et al. found that condensate dynamics of Sidekick, tuned by its conserved motif, contributes to its confined accumulation to tricellular junctions and molecular recruitment during epithelial dynamics, which eventually helps epithelial remodeling.

Spatial regulation of adhesion molecules is crucial for multicellular systems. Tricellular junctions (TCJs) represent the example. We found that gel-like condensation of a TCJ protein stabilizes its accumulation even in tissue dynamics, which ensures molecular recruitment and epithelial remodeling.

EMBL scientists found metabolism controls embryonic development tempo through signalling in a way separate from its established metabolic function. More research related to this signalling could illuminate how it guides cell fate, developmental timing -- even disease. www.embl.org/news/science...

A label-free method for measuring the composition of multicomponent biomolecular condensates - Nature Chemistry
Biomolecular condensates are made of multiple components but current techniques cannot capture their complex composition quantitatively. Now it has been shown that the dense-phase binodal point defini...

Out today in @nature.com: Together with the Honigmann, Shevchenko, Drobot and Hof labs, we present a general workflow for imaging the localization and transport of individual lipids in cells and mapping their metabolism. www.nature.com/articles/s41...

Excited to share our latest work out in @pnas.org! We show that the #SARSCoV2 nucleocapsid protein directly prevents DNA recognition of the immune sensor #cGAS by competing for DNA, which may delay early innate immune responses during infection. www.pnas.org/doi/epub/10.... #innateimmunity

The tricellular junction is a unique place where three or more cells contact. Here is our latest preprint showing the role of protein condensation in organizing molecular localization and function at tricellular junctions. www.biorxiv.org/content/10.1...

Condensation of Sidekick at tricellular junctions organizes mechanical forces for cell-cell adhesion remodeling
Epithelial morphogenesis relies on coordinated multicellular movements regulated by adhesion and force-generating molecules. It remains elusive how cells ensure organization of these molecules in spac...

Some small molecules modulate protein condensation in cells, but how? Our latest work shows a possible mechanism of action of the small molecule lipoamide. This molecule prevents condensation of stress granules whose components are found as protein aggregates in ALS. www.nature.com/articles/s41...
