Recently, we have demonstrated a predominant association of Rad26p with the coding sequences but not promoters of several GAL genes following transcriptional induction. Here, we show that the occupancy of histone H2A-H2B dimer at the coding sequences of these genes

The regulation of the Saccharomyces cerevisiae GAL genes in response to galactose as a source of carbon has served as a paradigm for eukaryotic transcriptional control over the last 50 years. Three proteins--a transcriptional activator (Gal4p), an inhibitor (Gal80p), and

Cells have evolved complex regulatory networks that reorganize gene expression patterns in response to changing environmental conditions. These changes often involve redundant mechanisms that affect various levels of gene expression. Here, we examine the consequences of enhanced mRNA degradation in

Bacterial artificial chromosome (BAC) recombineering using galK selection allows DNA cloned in Escherichia coli to be modified without introducing an unwanted selectable marker at the modification site. Genomes of some herpesviruses have a pair of inverted repeat sequences that makes

Expression plasmids for Saccharomyces cerevisiae offer a wide choice of vector copy number, promoters of varying strength and selection markers. These expression plasmids are usually shuttle vectors that can be propagated both in yeast and bacteria, making them useful in
