a database of cell signaling
If you study cell signaling, here is a comprehensive database of cell signaling offered through the American Association for the Advancement of Science and Science Magazine:

Components of cellular signaling pathways and their relations to one another–organized into pathways called Connections Maps–serve as the graphical interface into the database. This information is provided for this databased by scientists with expertise in a given field, designated as Pathway Authorities, and includes canonical or general data about cell signaling, as well as specific data about particular signaling processes in specific organisms and cells.
