Efficient use of accessibility in microRNA target prediction
Considering accessibility of the 3'UTR is believed to increase the precision of microRNA target predictions. We show that, contrary to common belief, ranking by the hybridization energy or by the sum of the opening and hybridization energies, used in currently available algorithms, is not an efficient way to rank predictions. Instead, we describe an algorithm which also considers only the acces...
متن کاملOptimal Use of Conservation and Accessibility Filters in MicroRNA Target Prediction
It is generally accepted that filtering microRNA (miRNA) target predictions by conservation or by accessibility can reduce the false discovery rate. However, these two strategies are usually not exploited in a combined and flexible manner. Here, we introduce PACCMIT, a flexible method that filters miRNA binding sites by their conservation, accessibility, or both. The improvement in performance ...
متن کاملViral microRNA target allows insight into the role of translation in governing microRNA target accessibility.
It is widely believed that functional mammalian microRNA (miRNA) recognition sequences are located preferentially in the 3' untranslated region (3'UTR) of target mRNAs. Nonetheless, putative miRNA target sites within coding regions have been found at lower frequency in genome-wide studies, and several have been genetically validated. To account for these findings, it has been proposed that tran...
متن کاملAccurate microRNA Target Prediction Using Detailed Binding Site Accessibility and Machine Learning on Proteomics Data
MicroRNAs (miRNAs) are a class of small regulatory genes regulating gene expression by targeting messenger RNA. Though computational methods for miRNA target prediction are the prevailing means to analyze their function, they still miss a large fraction of the targeted genes and additionally predict a large number of false positives. Here we introduce a novel algorithm called DIANA-microT-ANN w...
متن کاملComplications in mammalian microRNA target prediction.
In this chapter, we review evidence that at least three different types of microRNA (miRNA)-messenger RNA (mRNA) target interactions exist in mammals: short seeds, long seeds, and "perfect" hits (allowing G:U matches). Because new types of miRNAs are still being discovered, this list may not yet be complete.
