Measuring Protein-Protein Interactions in Cells using Nanoluciferase Bioluminescence Resonance Energy Transfer (NanoBRET) Assay.
Article in Methods in molecular biology (Clifton, N.J.), 2023. 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
Protein-protein interactions (PPIs) are increasingly recognized for their roles in functional cellular networks and their importance in disease-targeting contexts. Assessing PPI in the native cellular environment is challenging and requires specific and quantitative methods. Bioluminescence resonance energy transfer (BRET) is a biophysical process that can be used to quantify PPI. With Nanoluciferase bioluminescent protein as a donor and a fluorescent chloroalkane ligand covalently bound to HaloTag protein as an acceptor, NanoBRET provides a versatile and robust system to quantitatively measure PPI in living cells. BRET efficiency is proportional to the distance between the donor and acceptor, allowing for the measurement of PPI in real time. In this paper, we describe the use of NanoBRET to study specific interactions between proteins of interest in living cells that can be perturbed by using small-molecule antagonists and genetic mutations. Here, we provide a detailed protocol for expressing NanoLuc and HaloTag fusion proteins in cell culture and the necessary optimization of NanoBRET assay conditions. Our example results demonstrate the reliability and sensitivity of NanoBRET for measuring interactions between proteins, protein domains, and short peptides and quantitating the PPI antagonist compound activity in living cells.
