MicroRNAs are a family of small, non-coding RNAs that regulate gene expression in a sequence-specific manner. We propose a computational method to predict miRNA regulatory modules or groups of miRNAs and target genes that are believed to participate cooper ...
Small nucleolar RNAs (snoRNAs) play a key role in ribosomal RNA biogenesis, yet factors controlling their expression are unknown. We found that the majority of Saccharomyces snoRNA promoters display an aRCCCTaa sequence motif at the upstream border of a TA ...
Early ocular development is controlled by a complex network of transcription factors, cell cycle regulators, and diffusible signalling molecules. Together, these molecules regulate cell proliferation and apoptosis, and specify retinal fate. NKX5-3 is a hom ...
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) is an annotated non-redundant collection of eukaryotic POL II promoters, experimentally defined by a transcription start site (TSS). Access to promoter sequences is provided by pointers to positions in the correspondi ...
Nucleosome depletion at transcription start sites (TSS) has been documented genome-wide in multiple eukaryotic organisms. However, the mechanisms that mediate this nucleosome depletion and its functional impact on transcription remain largely unknown. We h ...
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 ...
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 ...
Chromatin structure and its impact on transcriptional activity represent one of the major revolutions in the biomedical field over the passed decade. The implications concern as much fundamental as clinically-oriented research; diseases and therapeutical s ...
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 ...
