Approaches to studying subnuclear organization and gene-nuclear pore interactions.

Many genes in budding yeast Saccharomyces cerevisiae associate with the nuclear pore complex (NPC), which impacts their location within the nucleus and their transcriptional regulation. To understand how eukaryotic genomes are spatially organized, we have used multiple approaches for analyzing the localization and transcription of genes. We have used these approaches to study the role of DNA elements in targeting genomic loci to the NPC and how these interactions regulate transcription, chromatin structure and the spatial organization of the yeast genome. These studies combine yeast molecular genetics with live-cell microscopy and biochemistry. Here, we present detailed protocols for these cytological and molecular approaches.
