Map identifiers between databases.
SYNTAX: biobtree_map(terms="ID", chain=">>source>>target")
- Chain MUST start with ">>"
- Source MUST match input ID type
ID TYPE → SOURCE:
- ENSG* → >>ensembl
- P*/Q*/O* → >>uniprot
- CHEMBL* → >>chembl_molecule
- GO:* → >>go
- MONDO:* → >>mondo
- HP:* → >>hpo
- HGNC:* or gene symbols → >>hgnc
SOME DRUG EXPLORATION PATHS:
- >>chembl_molecule>>chembl_target>>uniprot (drug targets)
- >>pubchem>>pubchem_activity>>uniprot (bioactivity)
- >>gtopdb_ligand>>gtopdb_interaction>>gtopdb>>uniprot (curated pharmacology with affinity data)
- >>ensembl>>reactome>>chebi (pathway chemicals - when no direct targets)
- Discover more via entry xrefs + EDGES
WARNING - GO terms with high xref_count (>100):
- Don't map GO → proteins → drugs (too many results)
- Instead: search drug class for condition → verify targets this GO term
DISEASE GENE PATTERNS:
- >>mondo>>gencc>>hgnc (curated)
- >>mondo>>clinvar>>hgnc (variant-based)
DISEASE → DRUG PATTERNS:
- >>mesh>>chembl_molecule (MeSH disease/condition → drugs with indications)
- >>mondo>>clinical_trials>>chembl_molecule (disease → trial drugs)
DISCOVERY APPROACH:
- Use biobtree_entry to see xrefs (what's connected)
- Use EDGES above to see where each dataset leads
- Build chains based on what connections exist for YOUR entity
RETURNS: mapped identifiers with dataset and name
