Identification of 15 candidate structured noncoding RNA motifs in fungi by comparative genomics

BMC Genomics
PMCID: 5640933
PMID: 29029611
DOI: 10.1186/s12864-017-4171-y

[…] mong structural elements that are only poorly conserved at the nucleotide level []. As a result, some successful computational search strategies for structured ncRNA candidates use algorithms such as QRNA [], RNAz [], or CMfinder [], which search for nucleotide covariation or other evidence of structure formation and conservation, rather than just searching for conserved sequence. A computational […]


Genome Wide Detection of Small Regulatory RNAs in Deep Sea Bacterium Shewanella piezotolerans WP3

Front Microbiol
PMCID: 5471319
PMID: 28663744
DOI: 10.3389/fmicb.2017.01093

[…] QRNA, A tool used for the detection of the conserved RNA secondary structures, including both ncRNA genes and cis-regulatory RNA structures.RNAz, A program for predicting structurally conserved and th […]


A Review on Recent Computational Methods for Predicting Noncoding RNAs

Biomed Res Int
PMCID: 5434267
PMID: 28553651
DOI: 10.1155/2017/9139504

[…] ogy-based methods is introduced based on structure conservations. Instead of sequence alignment, these methods use RNA secondary structure alignment to measure RNA similarity. Popular methods include QRNA [] and RNAz []. Specifically, QRNA compares query RNA with known RNAs using “three probabilistic pair-grammars: a pair stochastic context-free grammar modeling alignments constrained by structura […]


An improved method for identification of small non coding RNAs in bacteria using support vector machine

Sci Rep
PMCID: 5382675
PMID: 28383059
DOI: 10.1038/srep46070

[…] hand, zMFold was efficient in identifying positive, but not negative sRNAs. As a result, these methods generated either a high number of false negatives (FN) or false positives (FP). Other tools like QRNA and the one proposed by Arnedo et al. showed slightly better performance for the identification of both positive and negative sRNAs simultaneously, but their accuracies were less than optimums.In […]


A Review of Computational Methods for Finding Non Coding RNA Genes

PMCID: 5192489
PMID: 27918472
DOI: 10.3390/genes7120113

[…] sults compare favorably when tested on known RNAs from BLASTN queries []. McCutcheon et al. [] extended this work with experimental characterization. In addition to having a high false positive rate, QRNA fails to identify ncRNAs without significant structure while also picking up cis-regulatory mRNA structures. The results illustrate the importance of having multiple genome sequences at various e […]


Bacterial small RNAs in the Genus Rickettsia

BMC Genomics
PMCID: 4683814
PMID: 26679185
DOI: 10.1186/s12864-015-2293-7

[…] nd widely used programs to identify potential transcription factor binding sites [–]; Rho-independent terminators using RNAMotif [], TransTermHP [], and FindTerm []; conserved secondary structures by QRNA []; and conserved nucleotide sequences by BLASTN 2.0 []. Further, this program has been widely applied for sRNA predictions in several other bacteria attesting to its potential for accurately pre […]
