Thermogenomics: thermodynamic-based approaches to genomic analyses of DNA structure.
The postgenomic era is all about learning about function by comparing genomic sequences within and between organisms. This review describes an approach that applies detailed thermodynamic information, as opposed to sequence motif searches, to analyze genomes (thermogenomics) for the occurrence of sequences with the potential to form left-handed Z-DNA and those that bind the eukaryotic nuclear factor I (NFI) transcriptional regulators. Such thermogenomic strategies allow us to address the questions of whether Z-DNA forming sequences can potentially function in regulating transcription of eukaryotic genes and how such function may emerge relative to other GC-rich elements, such as NFI recognition sites, to become a transcriptional coactivator.
