The following drop-down menu allows for the browsing of data by specific biological pathway. This pathway heirarchy has been adopted from that used at Reactome. Each sub-pathway contains both BindingDB and Reactome links. BindingDB links go to binding data for proteins involved in a pathway. Note: Reactome "Reactions", as described on this page: http://www.reactome.org/userguide/Usersguide.html, are not included here.
