Structural Pockets and Interacting RNA-Associated Ligands (SPIRAL): A DSSR-enabled Meta-Analysis of RNA-Small Molecule Recognition (opens in new tab)

Small molecules that target structured RNA hold therapeutic promise across a wide range of diseases, yet the structural principles governing RNA-ligand recognition remain poorly defined. Here we present SPIRAL (Structural Pockets and Interacting RNA-Associated Ligands), a curated database of 1,098 RNA-small molecule structures from the Protein Data Bank covering 1,137 ligand-binding events across six functional RNA categories: riboswitches, ribozymes, synthetic aptamers, G-quadruplexes, ribos...
