A social network of human proteins

Scientists at the Max Planck Institute of Biochemistry in Martinsried near Munich and at the MPI of Molecular Cell Biology and Genetics in Dresden have now drawn a detailed map of human protein interactions. Using a novel mass spectrometric quantification method, the researchers determined the strength of each interaction. "Our data revealed that most interactions are weak, but critical for the structure of the entire network," explains Marco Hein, first author of the study. The paper has now be
