Identification of a Small Interface between the Methyltransferase and RNA Polymerase of NS5 that is Essential for Zika Virus Replication.
Article in Scientific reports, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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 spread of Zika virus (ZIKV) has caused an international health emergency due to its ability to cause microcephaly in infants. Yet, our knowledge of how ZIKV replicates at the molecular level is limited. For example, how the non-structural protein 5 (NS5) performs replication, and in particular whether the N-terminal methytransferase (MTase) domain is essential for the function of the C-terminal RNA-dependent RNA polymerase (RdRp) remains unclear. In contrast to previous reports, we find that MTase is absolutely essential for all activities of RdRp in vitro. For instance, the MTase domain confers stability onto the RdRp elongation complex (EC) and and is required for de novo RNA synthesis and nucleotide incorporation by RdRp. Finally, structure function analyses identify key conserved residues at the MTase-RdRp interface that specifically activate RdRp elongation and are essential for ZIKV replication in Huh-7.5 cells. These data demonstrate the requirement for the MTase-RdRp interface in ZIKV replication and identify a specific site within this region as a potential site for therapeutic development.
