Modularity is at the core of bioinformatics. Here we focused on two different building blocks: protein domains and exons. While protein domains enable us to study the protein‚s functions, exons allow us to understand the evolution of the former. However, a ...
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 ...
Vax1 and Vax2 have been implicated in eye development and the closure of the choroid fissure in mice and zebrafish. We sequenced the coding exons of VAX1 and VAX2 in 70 patients with anophthalmia/microphthalmia (A/M). In VAX1, we observed homozygosity for ...
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 ...
The expression of many proto-oncogenes, nuclear transcription factors and cytokines is regulated post-transcriptionally by specific interactions between distinct cis-elements within the mRNA and trans-acting factors that bind to these elements and thereby ...
Corrinoids (e.g. vitamin B12, cobalamin) represent a family of complex organometallic cofactors essential to the metabolism of microorganisms, animal and humans, and are involved in several enzymes such as isomerases, methyltransferases and reductive dehal ...
PURPOSE. Knowledge of genetic factors predisposing to age-related cataract is very limited. The aim of this study was to identify DNA sequences that either lead to or predispose for this disease. ...
Spliceosomal small nuclear ribonucleoproteins (snRNPs), comprised of small nuclear RNAs (snRNAs) in complex with snRNP-specific proteins, are essential for pre-mRNA splicing. Coilin is not a snRNP protein but concentrates snRNPs and their assembly intermed ...
We here present and demonstrate a novel technique based on isotachophoresis (ITP) for the quantification of global microRNA (miRNA) abundance in total RNA. We leverage the selectivity of ITP to concentrate miRNA and exclude longer RNA molecules from the fo ...
In prokaryotes and eukaryotes, most genes appear to be transcribed during short periods called transcriptional bursts, interspersed by silent intervals. We describe how such bursts generate gene-specific temporal patterns of messenger RNA (mRNA) synthesis ...
