Sgs1 helicase is required for efficient PCNA monoubiquitination and translesion DNA synthesis in Saccharomyces cerevisiae.
Article in Current genetics, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
DNA-damage tolerance (DDT) is employed by eukaryotes to deal with replication blocks on the template strand, and is divided into two parallel pathways that are activated by sequential ubiquitination of proliferating cell nuclear antigen (PCNA) at the Lys164 residue. Rad6-Rad18-mediated PCNA monoubiquitination promotes translesion DNA synthesis (TLS) and the monoubiquitinated PCNA can be further polyubiquitinated by an Mms2-Ubc13-Rad5 complex, leading to error-free lesion bypass. We previously reported that the DNA helicase Sgs1 is required for error-free lesion bypass, probably through the double-Holliday junction migration and subsequent resolution. Surprisingly, a synthetic genetic array (SGA) screen using rev1 and rev3 as baits did not reveal an anticipated synthetic effect with sgs1, indicating a possible involvement of Sgs1 in TLS. Here, we report detailed genetic analyses demonstrating that Sgs1 plays a key role in efficient TLS and that it is probably required for the signaling of DNA damage leading to PCNA monoubiquitination. These studies collectively illustrate that Sgs1 participates in both branches of DDT and possibly plays a role in pathway choice.
