Druggability Rationale: AHR demonstrates high druggability (0.90 score) despite being a transcription factor, supported by extensive structural data (14 PDB structures, 2.76 Å resolution), successful ligand-binding modulation by research tools (CH-223191, FICZ), and validated ligand-binding pocket enabling small molecule antagonism/agonism. The well-characterized ligand-binding domain provides a tractable binding interface distinct from DNA-binding regions, overcoming typical transcription factor undruggability limitations.
Mechanism: Small molecule modulators affecting ligand-dependent transcriptional activity

Selectivity & Safety Considerations

AHR selectivity is favorable as it lacks close paralogs, though off-target effects may arise from promiscuous ligand binding affecting other xenobiotic sensors (PXR, CAR). Tissue-specific expression variability and context-dependent transcriptional outcomes (pro- vs anti-inflammatory) present selectivity challenges at the functional level rather than molecular selectivity.
