HINT (High-quality INTeractomes) is a curated compilation of high-quality protein-protein interactions from 8 interactome resources (BioGRID,
the PDB). Interactions are filtered both systematically and manually to remove erroneous and low-quality interactions, and is updated every night. HINT can be used for individual queries as well as for batch downloads.
HINT has been updated. Version 4 is now online. Our databases are updated nightly.
