Adapter-mediated substrate selection for endoplasmic reticulum-associated degradation.
Article in The Journal of biological chemistry, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
During endoplasmic reticulum (ER)-associated degradation (ERAD), a relatively small number of ubiquitin ligases (E3) must be capable of ubiquitinating an assortment of substrates diverse in both structure and location (ER lumen, membrane, and/or cytosol). Therefore, mechanisms that operate independently of primary sequence determinants must exist to ensure specificity during this process. Here we provide direct evidence for adapter-mediated substrate recruitment for a virus-encoded ERAD E3 ligase, mK3. Members of an ER membrane protein complex that normally functions during major histocompatibility complex class I biogenesis in the immune system are required for mK3 substrate selection. We demonstrate that heterologous substrates could be ubiquitinated by mK3 if they were recruited by these ER accessory molecules to the proper position relative to the ligase domain of mK3. This mechanism of substrate recruitment by adapter proteins may explain the ability of some E3 ligases, including cellular ERAD E3 ligases, to specifically target the ubiquitination of multiple substrates that are unrelated in sequence.
