Pocket detection methods

Definition

Pocket detection methods are computational techniques used to identify and characterize cavities or pockets on the surface of biomolecules, particularly proteins. These pockets are critical for understanding how biomolecules interact with potential drug candidates, enabling the design of targeted therapeutics. By mapping these pockets, researchers can assess binding affinities and improve drug efficacy through structure-based drug design.
