Characteristics of MicroRNA Prediction Databases.

*Targetscan Conserved uses conservation, but it is not integrated into the context score.
§PITA does not explicitly use conservation in scoring targets. However, accessible microRNA binding sites tend to show high conservation.
¥picTar does have predictions for multiple microRNAs binding to a single 3′ UTR; however, that data was not used in this study.

* Targetscan 保守性分析模块（Targetscan Conserved）采用保守性信息，但并未将其整合至上下文评分体系中。
§ PITA 在靶标评分过程中并未显式使用保守性特征，不过可及的微小RNA（microRNA）结合位点往往呈现较高的保守性。
¥ picTar 可预测多个微小RNA（microRNA）结合至同一3′非翻译区（3′ UTR）的情况，但本研究并未使用该类数据。
