MDTE DB: A Database for MicroRNAs Derived from Transposable Element

MicroRNAs (miRNAs) are crucial regulators of gene expression at post-transcriptional level. Understanding origin and evolution of miRNAs will improve the current available algorithm for the prediction of novel miRNAs and their functions. Transposable elements (TEs) provide a natural mechanism for the origin of new miRNAs. In the paper, 2,583 miRNAs derived from TEs (MDTEs) were collected to construct a database named MDTE database (MDTE DB) for storing, searching, and analyzing MDTEs. The database provides a convenient source for studying the origin and evolution of miRNAs. Database URL:http://bioinf.njnu.edu.cn/MDTE/MDTE.php.
