Functional oligomerization of the Saccharomyces cerevisiae isoprenylcysteine carboxyl methyltransferase, Ste14p.
Article in The Journal of biological chemistry, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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 isoprenylcysteine carboxyl methyltransferase (Icmt) from Saccharomyces cerevisiae, also designated Ste14p, is a 26-kDa integral membrane protein that contains six transmembrane spanning segments. This protein is localized to the endoplasmic reticulum membrane where it performs the methylation step of the CAAX post-translational processing pathway. Sequence analysis reveals a putative GXXXG dimerization motif located in transmembrane 1 of Ste14p, but it is not known whether Ste14p forms or functions as a dimer or higher order oligomer. We determined that Ste14p predominantly formed a homodimer in the presence of the cross-linking agent, bis-sulfosuccinimidyl suberate. Wild-type untagged Ste14p also co-immunoprecipitated and co-purified with N-terminal-tagged His(10)-myc(3)-Ste14p (His-Ste14p). Furthermore, enzymatically inactive His-Ste14p variants L81F and E213Q both exerted a dominant-negative effect on methyltransferase activity when co-expressed and co-purified with untagged wild-type Ste14p. Together, these data, although indirect, suggest that Ste14p forms and functions as a homodimer or perhaps a higher oligomeric species.
