Transcriptional stochasticity in gene expression.
Due to the small number of copies of molecular species involved, such as DNA, mRNA and regulatory proteins, gene expression is a stochastic phenomenon. In eukaryotic cells, the stochastic effects primarily originate in regulation of gene activity. Transcription can be initiated by a single transcription factor binding to a specific regulatory site in the target gene. Stochasticity of transcript...
متن کاملTranscriptional repressors: multifaceted regulators of gene expression.
Through decades of research it has been established that some chromatin-modifying proteins can repress transcription, and thus are generally termed 'repressors'. Although classic repressors undoubtedly silence transcription, genome-wide studies have shown that many repressors are associated with actively transcribed loci and that this is a widespread phenomenon. Here, we review the evidence for...
متن کاملPost-Transcriptional Regulation of Papillomavirus Gene Expression
Papillomavirus genomes are transcribed as one large complex transcription unit with multiple promoters, two poly(A) sites (early and late), and considerable alternative splicing. As a result, there are multiple opportunities for post-transcriptional regulation of papillomavirus gene expression. Although this area has not been as extensively studied as transcriptional regulation, there are a few...
متن کاملPost-Transcriptional Control of Chloroplast Gene Expression
Chloroplasts contain their own genome, organized as operons, which are generally transcribed as polycistronic transcriptional units. These primary transcripts are processed into smaller RNAs, which are further modified to produce functional RNAs. The RNA processing mechanisms remain largely unknown and represent an important step in the control of chloroplast gene expression. Such mechanisms in...
متن کاملTranscriptional Control of Gene Expression by MicroRNAs
MicroRNAs (miRNAs) control gene expression in animals and plants. Like another class of small RNAs, siRNAs, they affect gene expression posttranscriptionally. While siRNAs in addition act in transcriptional gene silencing, a role of miRNAs in transcriptional regulation has been less clear. We show here that in moss Physcomitrella patens mutants without a DICER-LIKE1b gene, maturation of miRNAs ...
