Determination of the Rab27-Effector Binding Affinity Using a High-Throughput FRET-Based Assay.

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
Thus far, two Rab27 isoforms (Rab27a and Rab27b) have been identified that interact with their eleven downstream effectors proteins, preferentially in their GTP-bound state. In recent years, a number of studies has suggested roles for Rab27-effector protein interactions in the development of cancer cell invasion and metastasis, and immune and inflammatory responses. Here we develop an in vitro fluorescence resonance energy transfer (FRET)-based protein-protein interaction assay to report Rab27 protein interactions with their effectors. We particularly focus on determining the interaction of mouse (m) Synaptotagmin-like protein (Slp)1 and mSlp2 effector proteins with human (h)Rab27. Green fluorescent protein (GFP)-N-terminus Rab27 binding domains (m-Slp1 and m-Slp2) recombinant proteins were used as donor fluorophores, whereas mCherry-hRab27a/b recombinant proteins were used as acceptor fluorophores. The conditions of this assay were validated and optimized, and the specificity of the assay was confirmed. Accordingly, this assay can be used to assess and identify key determinants and/or candidate inhibitors of Rab27-effector interactions.
