Data used for benchmarking the use of homology based predicitons can be found here for human, rat, mouse and cow.

CHEMBL_Uniprot.txt: Protein target ID mapping between ChEMBL and Uniprot, based on the ChEMBL website, and containing information only for protein targets used in this validation. Members of protein complexes are listed with the '&' symbol.

For each organisms:
- validation_interactions.txt:	List of small molecule-protein interactions. Column 1 gives the small molecule (ChEMBL ID), column 2 the target (ChEMBL ID), columns 3 the Uniprot name of the target, column 4 gives 1 for a reported binding and 0 for non-binding.
- validation_molecules.txt: List of SMILES for each molecule in the interaction dataset
- validation_target.txt: List of targets (UniProt ID).
