Abstract

DESCRIPTION (provided by applicant): Recently, genomes have been recognized to adopt preferred physical architectures that are evolutionarily conserved and cell type specific. We developed a method for characterizing long-range inter- and intra- chromosomal interactions on a genome-wide scale. Our method is based on chromatin conformation capture (3C) but unlike 3C (or other derivative technologies), makes no a priori assumptions regarding interacting genetic elements. Due to the large size of mammalian genomes we initially validated our approach in haploid Saccharomyces cerevisiae. In this application we propose to use this method to understand the relationship between genome architecture and allele specific expression in mammalian development.
