Widespread occurrence of non-canonical transcription termination by human RNA polymerase III

Human RNA polymerase (Pol) III-transcribed genes are thought to share a simple termination signal constituted by four or more consecutive thymidine residues in the coding DNA strand, just downstream of the RNA 3'-end sequence. We found that a large set of ...

Krüppel-associated box domain-zinc finger proteins (KRAB-ZFPs) are tetrapod-specific transcriptional repressors encoded in the hundreds by the human genome. In order to explore their as yet ill-defined impact on gene expression, we developed an ectopic rep ...

Protein phosphatase 1 regulates the histone code for long-term memory

Johannes Gräff

Chromatin remodeling through histone posttranslational modifications (PTMs) and DNA methylation has recently been implicated in cognitive functions, but the mechanisms involved in such epigenetic regulation remain poorly understood. Here, we show that prot ...

Circadian gene expression is resilient to large fluctuations in overall transcription rates

Michaël Unser, Felix Naef, Daniel Sage, Thomas d'Eysmond

Mammalian circadian oscillators are considered to rely on transcription/translation feedback loops in clock gene expression. The major and essential loop involves the autorepression of cryptochrome (Cry1, Cry2) and period (Per1, Per2) genes. The rhythm-gen ...

The human SPT20-containing SAGA complex plays a direct role in the regulation of endoplasmic reticulum stress-induced genes

One of the central questions in eukaryotic transcription is how activators can transmit their signal to stimulate gene expression in the context of chromatin. The multisubunit SAGA coactivator complex has both histone acetyltransferase and deubiquitination ...

2008

Cancer cells have a raised cellular metabolism, including increased protein biosynthesis. Three new studies now show that the oncoprotein Myc, known to drive cell division, also enhances ribosomal RNA synthesis by RNA polymerase I in addition to controllin ...

The Eukaryotic Promoter Database EPD: the impact of in silico primer extension

Philipp Bucher, Rouayda Cavin Perier

The Eukaryotic Promoter Database (EPD) is an annotated non-redundant collection of eukaryotic POL II promoters, experimentally defined by a transcription start site (TSS). There may be multiple promoter entries for a single gene. The underlying experimenta ...

2004

We investigated the expression of several mRNAs in exoerythrocytic and erythrocytic stages of Plasmodium yoelii in infected mice, focusing our attention on genes thought to be involved in signal transduction (like pypka and pymap-1, encoding homologues of ...

The Eukaryotic Promoter Database (EPD): recent developments

Philipp Bucher, Rouayda Cavin Perier

The Eukaryotic Promoter Database (EPD) is an annotated non-redundant collection of eukaryotic POL II promoters, for which the transcription start site has been determined experimentally. Access to promoter sequences is provided by pointers to positions in ...

Effect of transcription inhibitors on the iron-dependent degradation of transferrin receptor mRNA

Lukas Kühn

Transferrin receptor (TfR) mRNA expression is tightly linked to intracellular iron levels. Upon iron deprivation, the iron regulatory protein (IRP) stabilizes TfR mRNA by binding to stem-loop structures in its 3'-untranslated region, whereas increased iron ...
