Linking the proteins--elucidation of proteome-scale networks using mass spectrometry.

Delphine Pflieger, Florence Gonnet, Sergio de la Fuente van Bentem, Heribert Hirt, Alberto de la Fuente,

Proteomes are intricate. Typically, thousands of proteins interact through physical association and post-translational modifications (PTMs) to give rise to the emergent functions of cells. Understanding these functions requires one to study proteomes as "systems" rather than collections of individual protein molecules. The abstraction of the interacting proteome to "protein networks" ... Read more >>
