Using Pathway Commons:

Biologists: Browse and search pathways across multiple valuable public pathway databases.

Computational biologists: Download an integrated set of pathways in BioPAX format for global analysis.

Software developers: Build software on top of Pathway Commons using our web service API. Download and install the cPath software to create a local mirror.

Current Data Sources:

Pathway Commons currently contains the following data sources (batch download):

Pathway Commons Quick Stats:
Number of Pathways: 1,668
Number of Interactions: 442,182
Number of Physical Entities: 86,282
Number of Organisms: 414

Integration of additional data sources is planned in the near future. For a comprehensive directory of interaction and pathway databases, please refer to Pathguide.
