Ribosome customization and functional diversification among P-stalk proteins regulate late poxvirus protein synthesis.
Article in Cell reports, 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
Growing evidence suggests that ribosomes selectively regulate translation of specific mRNA subsets. Here, quantitative proteomics and cryoelectron microscopy demonstrate that poxvirus infection does not alter ribosomal subunit protein (RP) composition but skews 40S rotation states and displaces the 40S head domain. Genetic knockout screens employing metabolic assays and a dual-reporter virus further identified two RPs that selectively regulate non-canonical translation of late poxvirus mRNAs, which contain unusual 5' poly(A) leaders: receptor of activated C kinase 1 (RACK1) and RPLP2. RACK1 is a component of the altered 40S head domain, while RPLP2 is a subunit of the P-stalk, wherein RPLP0 anchors two heterodimers of RPLP1 and RPLP2 to the large 60S subunit. RPLP0 was required for global translation, yet RPLP1 was dispensable, while RPLP2 was specifically required for non-canonical poxvirus protein synthesis. From these combined results, we demonstrate that poxviruses structurally customize ribosomes and become reliant upon traditionally non-essential RPs from both ribosomal subunits for efficient initiation on their late mRNAs.
