Initial Datasets of Complexes and Direct Interactions.

For protein complexes (PC set), the table shows the numbers of total evidences containing four or more proteins, compositionally unique (non-redundant) complexes, participating proteins and reporting publications. The parameter (see Methods and Fig. 2) is derived from the distribution of the number of complexes per protein. For direct interactions, the table shows the numbers of total pairs, participating proteins and reporting publications. Note that a publication may report both pull down experiments and direct interactions. The final column presents the parameter , the median number of direct interactions per protein.
