Study of the regulatory architecture of vertebrate genomes is providing one of the biggest challenges of the post-genomic era. Fish-mammal genomic comparisons have proved powerful in identifying conserved non-coding elements likely to be distal cis-regulatory modules such as enhancers, silencers or insulators. In addition, there is increasing evidence that such elements are strongly associated with genes involved in transcriptional regulation and development. Here, by using a targeted multiple-alignment strategy of orthologous genomic sequence from the Japanese pufferfish Fugu rubripes together with that of a number of mammals, I identified a large set of conserved non-coding elements (CNEs) surrounding more than 100 regulator genes involved in early development. To facilitate a further in-depth analysis of these elements for this study and public use, a relational database CONDOR (database of COnserved NoncoDing Orthologous Regions) and front-end were designed to store and access this data together with associated functional data issuing from wet-lab experimentation. The database can be accessed at condor.crick.ac.uk.
Using the database, I studied a number of evolutionary and sequence-based aspects of these intriguing elements and found they are distinct in many ways from other functional sequences such as coding exons. In addition, a small proportion of these elements show sequence similarity to other parts of the genome and appear to be associated with nearby paralogous genes that date back to the large-scale duplication events at the origin of vertebrates. Finally I carried out a comparative analysis of CNEs identified around seven pairs of Fugu developmental genes that derive from whole-genome duplication early in the teleost lineage. Presence of shared and distinct CNEs between duplicated genes suggest they are likely to have undergone a process of regulatory subfunctionalisation the extent of which differs between duplicate pairs.
