PubChem BioAssay Submissions: We initiated the complete and regular upload of all BindingDB data to PubChem in the form of Bioassays. This procedure has so far generated 13,541 Assay IDs, of which 10,210 come from patents. Archiving of CSAR and D3R Datasets: BindingDB provides stable access to the protein-ligand datasets developed and used in the course of the CSAR and D3R prediction challenges (www.bindingdb.org/rwd/bind/ByD3R.jsp).
