Evidence that the COOH terminus of human presenilin 1 is located in extracytoplasmic space.
Article in American journal of physiology. Cell physiology, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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 polytopic membrane protein presenilin 1 (PS1) is a component of the gamma-secretase complex that is responsible for the intramembranous cleavage of several type I transmembrane proteins, including the beta-amyloid precursor protein (APP). Mutations of PS1, apparently leading to aberrant processing of APP, have been genetically linked to early-onset familial Alzheimer's disease. PS1 contains 10 hydrophobic regions (HRs) sufficiently long to be alpha-helical membrane spanning segments. Most topology models for PS1 place its COOH terminal approximately 40 amino acids, which include HR 10, in the cytosolic space. However, several recent observations suggest that HR 10 may be integrated into the membrane and involved in the interaction between PS1 and APP. We have applied three independent methodologies to investigate the location of HR 10 and the extreme COOH terminus of PS1. The results from these methods indicate that HR 10 spans the membrane and that the COOH terminal amino acids of PS1 lie in the extracytoplasmic space.
