TUG protein acts through a disordered region to organize the early secretory pathway.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The Endoplasmic Reticulum (ER)-Golgi Intermediate Compartment (ERGIC) is a network of tubules and vesicles known for producing COPI vesicles and receiving COPII vesicles from the ER. Much about its identity, stability, and regulation remains unknown. Here, we show that TUG (UBXN9, Aspscr1) protein, a central regulator of GLUT4 trafficking, localizes to the ERGIC, and that its deletion enhances anterograde flux of a model soluble cargo protein. TUG deletion redistributes ERGIC markers to the cis-Golgi and alters Golgi morphology. TUG forms biomolecular condensates in vitro and contains a central disordered region that mediates its recruitment to ERGIC membranes. A distinct N-terminal region mediates its oligomerization in cells. TUG deletion disrupts ERGIC-dependent processes, including autophagy and collagen secretion, and alters the targeting of the CFTR chloride channel. We conclude that TUG organizes and stabilizes ERGIC membranes to support their roles in diverse secretory and degradative membrane trafficking pathways.
