WikiPathways uses BridgeDb to let you search for identifiers. For example
- Go to http://www.wikipathways.org
- Sign up for an account (you don't have to provide your email address, you can create a dummy account just to test it)
- Go to the Sandbox page, you're free to edit this pathway
- Click the Edit button just below the pathway
- Create a new datanode by clicking on the "gene" or "metabolite" toolbar buttons, and then clicking in the pathway area
- Double-click on the datanode you've just created
- Enter a search term and click Search. For example, search for "Glucose" or search for "INSR" (for Insulin Receptor)
- A list of identifiers should pop up. There identifiers are provided by BridgeDb. You can select one to annotate your pathway element.
- If you click on the backpage tab, you should see links for all kinds of cross-references for your pathway element. There are provided by BridgeDb as well.
WikiPathways does not let the user configure the identifier mapping services. It always uses a stack of two mapping services: one for metabolites and one for genes and proteins that depend on the selected species.
