title: Systematic functional assessment of human protein-protein interaction maps.
abstract: Protein-protein interaction maps can contribute substantially to the discovery of protein cooperation patterns in the cell. Recently, several large-scale human protein-protein interaction maps have been generated using experimental or computational approaches. Evaluation of these maps is likely to provide a better understanding of human biology. However, careful analysis is needed, as the comparison of interaction maps of lower eukaryotes showed a surprising divergence between different maps. Here, we present a first systematic functional assessment of eight currently available large-scale human protein-protein interaction maps. The analysis shows that these maps include a large number of common proteins, but only a small number of common interactions. We detected several types of biases that need to be considered in the future utilization of these maps.
