Competition between sumoylation and ubiquitination of serine hydroxymethyltransferase 1 determines its nuclear localization and its accumulation in the nucleus.

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
Serine hydroxymethyltransferase 1 (SHMT1) expression limits rates of de novo dTMP synthesis in the nucleus. Here we report that SHMT1 is ubiquitinated at the small ubiquitin-like modifier (SUMO) consensus motif and that ubiquitination at that site is required for SHMT1 degradation. SHMT1 protein levels are cell cycle-regulated, and Ub-SHMT1 levels are lowest at S phase when SHMT1 undergoes SUMO modification and nuclear transport. Mutation of the SUMO consensus motif increases SHMT1 stability. SHMT1 interacts with components of the proteasome in both the nucleus and cytoplasm, indicating that degradation occurs in both compartments. Ubc13-mediated ubiquitination is required for SHMT1 nuclear export and increases stability of SHMT1 within the nucleus, whereas Ubc9-mediated modification with Sumo2/3 is involved in nuclear degradation. These data demonstrate that SUMO and ubiquitin modification of SHMT1 occurs on the same lysine residue and determine the localization and accumulation of SHMT1 in the nucleus.
