UCNEbase - A database for ultraconserved noncoding elements and genomic regulatory blocks (Release version 1.0.1 - March 2023)

UCNEbase provides information on the evolution and genomic organization of
ultra-conserved non-coding elements (UCNEs) in multiple vertebrate species.
It currently covers 4351 such elements in 18 different species. Around half
of these elements are located within intergenic regions (2'139) and the rest
are located within non-coding parts of genes: introns (1'713) and UTRs (499).
The majority of UCNEs are supposed to be transcriptional regulators of key
developmental genes.

Detailed description of the resource can be found in the UCNEbase_doc.pdf file
included in this directory.
