Citations Peer-reviewed manuscripts describing our work. Elements are tested out of their genomic context and may not produce the same patterns of expression as they would in the genome, possibly due to structural or steric influences or interactions with other elements not present in the assay. Altschul S. The web site therefore provides a number of approaches by which the data can be accessed, visualised and downloaded. The genomic size of the identified UGRBs also varies significantly from 4. Figure 4. Hudson R. Arbor Biosciences has even made a discounted "pilot" sized kit available for labs who want to do some test enrichments. The second part contains information about homologous regions in other vertebrates.

    Some existing resources are restricted to selected genomic regions. Several comparative studies on whole vertebrate genomes uncovered non-coding sequences that exhibit extremely high conservation.

    Experimental studies in transgenic animals suggest that most of these sequences act as tissue-specific enhancers during developmental processes 6—8.

    Clustering CNEs by their spatial and temporal specific enhancer activity to look for similar common motifs may therefore allow us to begin to discern the language of developmental enhancers. In detail:.

The website is designed to make the interrogation and visualisation of this data as user friendly and intuitive as possible, catering for both lab-based investigators interested in biological function and bioinformatics researchers interested in sequences datasets of high regulatory potential. In some cases, synteny across paralogous blocks was used to redefine the extension of individual UGRBs.

    In reality, we often find one cluster plus a few isolated orthologous UCNEs located on sequence contigs not assigned to chromosomes.

    In most cases this is the only trans-dev gene in the vicinity although in a number of cases CNEs are interspersed within clusters of related trans-dev genes e. Below are two bait set designs that we have used 1 to understand relationships among the early diverging teleosts Faircloth et al.

    The large evolutionary distance between fish and mammals means that even the slowest evolving DNA has diverged sufficiently to significantly improve the signal to noise ratio in genomic alignments. To facilitate their study, CONDOR supplies an extra facility that allows the CNEs in these duplicated regions to be compared side-by-side highlighting those CNEs that have partitioned to a specific gene copy as well as those conserved to some degree in both copies.

    The baits designs described below derive from Faircloth Despite a common theme, the scopes of these resources are quite different which makes a direct comparison difficult.
