EPPS β Ensemble Persistent Pocket Scoring
A research tool for finding candidate drug-binding sites on flexible, intrinsically disordered proteins β the kind implicated in Parkinson's, Alzheimer's, and ALS that are often considered "undruggable" because they never hold a single fixed shape. Instead of one static structure, EPPS analyzes an entire ensemble of a protein's conformations and scores each residue by how persistently it lines a pocket β surfacing transient, cryptic binding sites that conventional single-structure methods miss.
- Weight each conformation by physical realism.
- Map per-residue pocket tendency across the weighted ensemble.
- Learn the structural signatures that precede pocket formation.
- Score β combine into a final per-residue druggability value.
Delivered as an interactive web tool: enter a protein's PDB ID and get a live, explorable analysis β 3D conformational states, a druggability landscape, and an exportable report. For proteins lacking an experimental ensemble, EPPS can generate one from a single structure via normal-mode analysis or molecular dynamics. Predictions are benchmarked against experimentally validated cryptic-pocket datasets using residue-level metrics, on the same footing as established methods in the field.
