Context dependent deposition and regulation of mRNAs in P bodies

PMCID: 5752201
PMID: 29297464
DOI: 10.7554/eLife.29815.043

[…] Secondary structure motifs in the 3’ untranslated regions (UTRs) of transcripts, overrepresented among differentially enriched mRNAs for each stress condition, were identified using NoFold () version 1.0. 3’ UTR sequences were extracted from the biomart project (RRID:SCR_002987) ( by selecting 300 base pairs (bp) downstream of the coding sequence (CDS). The int […]

[…] ut transformation, and subjected to OPTICS clustering as implemented in the dbscan CRAN repository with a range of parameters (see Fig.  , ).Other tested RNA clustering approaches were GraphClust and NoFold. We ran GraphClust version 0.7.6 inside the Docker image provided with RNAscClust with default parameters. NoFold version 1.0.1 uses 1973 Rfam CMs by default as empirical feature space. For the […]


Functional annotation of structural ncRNAs within enhancer RNAs in the human genome: implications for human disease

Sci Rep
PMCID: 5686184
PMID: 29138457
DOI: 10.1038/s41598-017-15822-7

[…] en by REAPR and RNAz. The predicted loci in the candidate set were identified by a local BLASTN search against the Rfam database using the default parameters. The whole predicted set was clustered by NoFold into the RNA empirical structure space (RESS). The top-ranked CMs were used to rank the most similar known structures to each novel structure in the cluster. […]
