Murine gammaherpesvirus 68 ORF75c contains ubiquitin E3 ligase activity and requires PML SUMOylation but not other known cellular PML regulators, CK2 and E6AP, to mediate PML degradation.
Article in Virology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 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
All gammaherpsviruses encode at least one gene related to the cellular formylglycinamide ribonucleotide amidotransferase (FGARAT) enzyme but their biological roles are relatively unknown. The murine gammaherpesvirus 68 (MHV68) vFGARAT, ORF75c, mediates a proteasome-dependent degradation of the antiviral promyelocytic leukemia (PML) protein by an unknown mechanism, which is addressed in this study. We found that ORF75c interacts weakly with PML and SUMO-modified forms of PML are important for its degradation by ORF75c. ORF75c-mediated PML degradation was not dependent on two known cellular regulators of PML stability, Casein kinase II (CK2) and human papilloma virus E6-associated protein (E6AP). Finally, ORF75c had self-ubiquitination activity in vitro and its expression increased levels of ubiquitinated PML in transfected cells. Taken together, the evidence accumulated in this study provides new insights into the function of a vFGARAT and is consistent with a model in which ORF75c could mediate direct ubiquitination of PML resulting in its degradation by the proteasome.
