Abstract

Significance: Following initial discoveries of noncovalent associations surviving in the gas phase, only a few practitioners pursued this research area. Today scientists around the world are using these approaches to ascertain the heterogeneity and stoichiometry of proteins within complexes. Recent developments further highlight opportunities for studying the effects of protein glycosylation on antibody–antigen interactions and drug binding, as well as site-directed mutagenesis and posttranslational modification on membrane protein interfaces. As a result of many developments over the last two decades, mass spectrometry of protein complexes has exploded and is now undertaken not just in dedicated research laboratories in academia, but also in pharmaceutical and biotechnology companies. It is therefore timely to trace the history of these developments in this personal perspective.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Many challenging analytes such as membrane proteins, intrinsically disordered proteins, highly dynamic or heterogeneous complexes, or very large systems such as intact virus capsids can all be investigated using native MS, as well as their associated proteoforms.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
