Description

This track contains genome-wide maps of Repressor Element 1-Silencing Transcription Factor (REST) binding sites in mouse stem cells, generated by the Stem Cell and Developmental Biology Group at the Genome Institute of Singapore. REST is a zinc finger transcriptional repressor that regulates a large cohort of neural genes throughout development. Aberrant REST activity has been implicated in various disease states, including cancer, epilepsy, Huntington's disease and cardiovascular disease.

Display Conventions and Configuration

  • The Embryonic Stem Cells only PET clusters (marked: ESC_only) are colored red.
  • The Embryonic and Neural Stem Cells PET clusters (marked: ESC_NSC) are colored blue.

Methods

The ChIP-PET (chromatin immunoprecipitation coupled to paired-end di-tagging) method was used to identify genomic loci occupied by REST. 36 bp PETs generated from ChIP DNA fragments enriched for REST binding regions were sequenced using the high-throughput 454 sequencing technology. REST binding sites were defined as those having at least five overlapping PETs (PET5+). Mapping was carried out in two isogenic cell lines: the mouse embyronic stem cell E14, and the neural stem cell line NS5. The REST binding sites are divided into two categories:

  • ESC and NSC shared sites, "ESC_NSC" (PET5+ in ESC, PET2+ in NSC)
  • ESC-specific sites, "ESC_only" (PET5+ in ESC, PET<2 in NSC)
Negligible numbers of NS-only sites were identified. The coordinates displayed represent the PET minimal overlap region, defined as the region that is overlapped in common by all PETs constituting a cluster.
