Drug-Target Interaction Prediction

Drug-Target Interaction Prediction

A skill for computational prediction of drug-target interactions (DTI), covering molecular docking, machine learning-based binding affinity prediction, compound library screening, and target identification using cheminformatics and structural biology tools.
