MetabolomicsMetabolome variability for two Mediterranean sponge species of the genus Haliclona: specificity, time, and space

INTRODUCTION: The study of natural variation of metabolites brings valuable information on the physiological state of the organisms as well as their phenotypic traits. In marine organisms, metabolome variability has mostly been addressed through targeted studies on metabolites of...

GenomicsA genome-wide analysis of Cas9 binding specificity using ChIP-seq and targeted sequence capture
Clustered regularly interspaced short palindromic repeat (CRISPR) RNA-guided nucleases have gathered considerable excitement as a tool for genome engineering. However, questions remain about the specificity of their target site recognition. Most previous studies have examined predicted off-target bi...

GenomicsDNA specificity determinants associate with distinct transcription factor functions
To elucidate how genomic sequences build transcriptional control networks we need to understand the connection between DNA sequence and transcription factor binding and function. Binding predictions based solely on consensus predictions are limited because a single factor can use degenerate sequenc...

TranscriptomicsCas9 target DNA specificity in vitro and in vivo (S. cerevisiae)
Cas9, a CRISPR RNA-guided nuclease, has been rapidly adopted as a tool for biochemical and genetic manipulation of DNA. Although Cas9 offers remarkable specificity and versatility for genome manipulation, mis-targeted events occur. To extend the understanding of Cas9 target::homology requirements, w...

TranscriptomicsEvaluation of methods for modeling transcription factor sequence specificity
Genomic analyses often involve scanning for potential transcription-factor (TF) binding sites using models of the sequence specificity of DNA binding proteins. Many approaches have been developed to model and learn a protein’s binding specificity by representing sequence motifs, including the gaps a...

TranscriptomicsVariation in homeodomain DNA-binding revealed by high-resolution analysis of sequence preferences
Most homeodomains are unique within a genome, yet many are highly conserved across vast evolutionary distances, implying strong selection on their precise DNA-binding specificities. We determined the binding preferences of the majority (168) of mouse homeodomains to all possible 8-base sequences, re...

TranscriptomicsA modified bacterial one-hybrid system yields improved quantitative models of transcription factor specificity
We examine the use of high-throughput sequencing on binding sites recovered using a bacterial one-hybrid (B1H) system and find that improved models of transcription factor (TF) binding specificity can be obtained compared to standard methods of sequencing a small subset of the selected clones. We ca...

GenomicsAsymmetry of STAT action in driving IL-27 and IL-6 transcriptional outputs and cytokine specificity
IL-6 and IL-27 have antagonistic and overlapping functions, signal through a shared receptor subunit and employ the same downstream STAT proteins. To evaluate the degree of specificity and redundancy for these cytokines, we quantified global transcriptomic changes induced by the two cytokines and de...

TranscriptomicsRNA-seq reveals that Air1 and Air2 control TRAMP substrate specificity for nuclear RNA surveillance
The Saccharomyces cerevisiae TRAMP4 and TRAMP5 complexes, which consist of the poly(A) polymerase Trf4 or Trf5, respectively, the zinc knuckle proteins Air1 or Air2, and the RNA helicase Mtr4, play a critical role in nuclear RNA surveillance. Although it is known to enhance the nuclease activity of ...
