Abstract
Accurately predicting poly(A) signals (PASs) is one of important topics in bioinformatics for high-quality genome annotation and transcription regulation mechanism investigation. In this study, we identified a powerful physicochemical property of DNA sequence for computationally predicting PASs using machine learning technologies. On the basis of this feature, we built a PAS prediction model by capturing the position-specific information from the region surrounding PASs. The cross-validation results demonstrated that the prediction accuracies of our constructed model on 12 categories of human PASs are comparable to those of recently published PAS predictor Dragon PolyA Spotter. Further analysis revealed that the region 25 nucleotides downstream of PASs is the most important region for the accurate prediction of PASs.
