Starting in March, Nature Methods strongly recommends deposition of proteomics data to public repositories before manuscript submission. An Editorial in the March issue describes the motivation of this decision and comments on the public repositories that are now available to proteomics researchers.
We welcome your comments on this move.
Last December we published an Article by Simon Davis and colleagues challenging the conventional methodology being used in BRET studies that detect dimerization of G protein coupled receptors. The conclusions were contested in a Correspondence by Michel Bouvier and colleagues. In a new Correspondence, a former member of the Bouvier lab further argues against the results and conclusions of the Davis study with experimental results using the 'Type 2' BRET assay of Davis and colleagues.
If you were given a choice between a large protein-protein interaction data set obtained by high-throughput experiments and another data set extracted from a collection of small-scale experiments via literature mining, which one would you trust more?

Using a new quantitative framework for evaluation of receptor dimerization using bioluminescence energy transfer (BRET), Simon Davis and colleagues at the University of Oxford present evidence that the signals arising from BRET measurements, and interpreted as evidence of dimerization, are the result of random interactions and not evidence of stable complexes.
