Aim: To develop a reliable computational approach for predicting potential drug targets based merely on protein sequence.
Methods: With drug target and non-target datasets prepared and 3 classification algorithms (Support Vector Machine, Neural Network and Decision Tree), a multi-algorithm and multi-model based strategy was employed for constructing models to predict potential drug targets.
Results: Twenty one prediction models for each of the 3 algorithms were successfully developed. Our evaluation results showed that ~30% of human proteins were potential drug targets, and ~40% of putative targets for the drugs undergoing phase II clinical trials were probably non-targets. A public web server named D3TPredictor (http://www.d3pharma.com/d3tpredictor) was constructed to provide easy access.
Conclusion: Reliable and robust drug target prediction based on protein sequences is achieved using the multi-algorithm and multi-model strategy.
Keywords: drug target; protein sequence; multi-algorithm and multi-model strategy; web server; support vector machine; neural network; decision tree
