Description

NCBI recently announced a new release of functional regulatory elements. NCBI is now providing RefSeq and Gene records for non-genic functional elements that have been described in the literature and are experimentally validated. Elements in scope include experimentally-verified gene regulatory regions (e.g., enhancers, silencers, locus control regions), known structural elements (e.g., insulators, DNase I hypersensitive sites, matrix/scaffold-associated regions), well-characterized DNA replication origins, and clinically-significant sites of DNA recombination and genomic instability. Priority is given to genomic regions that are implicated in human disease or are otherwise of significant interest to the research community. Currently, the scope of this project is restricted to human and mouse. The current scope does not include functional elements predicted from large-scale epigenomic mapping studies, nor elements based on disease-associated variation.

Display Conventions and Configuration

Functional elements are colored by Sequence Ontology (SO) term using the same scheme as NCBI's Genome Data Viewer:

  • Regulatory elements (items labeled by INSDC regulatory class)
  • Protein binding sites (items labeled by bound moiety)
  • Mobile elements
  • Recombination features
  • Sequence features
  • Other

Methods

NCBI manually curated features in accordance with International Nucleotide Sequence Database Collaboration (INSDC) standards. Features that are supported by direct experimental evidence include at least one experiment qualifier with an evidence code (ECO ID) from the Evidence and Conclusion Ontology, and at least one citation from PubMed. Currently 971 distinct PubMed citations are included in this track.
