Searching the coding region for microRNA targets

Jiri Vanicek, Ray Marcel Marin Florez, Miroslav Sulc

Finding microRNA targets in the coding region is difficult due to the overwhelming signal encoding the amino acid sequence. Here, we introduce an algorithm (called PACCMIT-CDS) that finds potential microRNA targets within coding sequences by searching for ...

Highly Specific Methods for the Prediction of Genes Regulated by MicroRNAs

Ray Marcel Marin Florez

MicroRNAs (miRNAs) comprise a large set of short noncoding RNAs that bind to messenger RNAs (mRNAs) to reduce their translation into functional proteins. Computational prediction of miRNA targets is the first stage in the discovery and validation of new re ...

Real-Time mRNA Measurement during an

Sebastian Maerkl, Henrike Marie Niederholtmeyer

In vitro transcription and translation reactions have become popular for a bottom-up approach to synthetic biology. Concentrations of the mRNA intermediate are rarely determined, although knowledge of synthesis and degradation rates could facilitate ration ...

A computational framework for the design of optimal protein synthesis

Vassily Hatzimanikatis, Julien Racle, Jan Overney

Despite the establishment of design principles to optimize codon choice for heterologous expression vector design, the relationship between codon sequence and final protein yield remains poorly understood. In this work, we present a computational framework ...

Wiley-Blackwell2012

Enantiopure 1,3-diethynylallenes were used as monomers in the construction of monodisperse oligomers and cyclooligomers. The open-chain structures show a non-linear increase in the intensity of the chiroptical properties as the no. of monomeric units incre ...

Fragile X syndrome (FXS) is an X-linked condition associated with intellectual disability and behavioral problems. It is caused by expansion of a CGG repeat in the 5' untranslated region of the fragile X mental retardation 1 (FMR1) gene. This mutation is a ...

Vibrational entropy and the structural organization of proteins

Paolo De Los Rios, Francesco Piazza

In this paper we analyze the vibrational spectra of a large ensemble of non-homologous protein structures by means of a novel tool, that we coin Hierarchical Network Model (HNM). Our coarse-grained scheme accounts for the intrinsic heterogeneity of force c ...

New methods for the investigation of RNA refolding by NMR spectroscopy

Philipp Wenter

A detailed characterization of the time scales and mechanisms by which RNA molecules change their folding structure upon binding of metabolites or during catalysis is important for the understanding of the different biological functions of RNA. The folding ...

Destabilization of interleukin-6 mRNA requires a putative RNA stem-loop structure, an AU-rich element, and the RNA-binding protein AUF1

Lukas Kühn, Barbara Grisoni-Neupert

Interleukin-6 mRNA is unstable and degraded with a half-life of 30 min. Instability determinants can entirely be attributed to the 3' untranslated region. By grafting segments of this region to stable green fluorescent protein mRNA and subsequent scanning ...

The fourth helical secondary structure of β-peptides: The (P)-28-helix of a β-hexapeptide consisting of (2R,3S)-3-amino-2-hydroxy acid residues

Karl Gademann

The authors report compelling evidence for the formation of a fourth type of helical secondary structure of a beta-peptide in MeOH, and this phenomenon occurs if each amino acid has a hydroxy group in the 2-position. 2D-NMR expts. of terminally-protected b ...
