Summary
This genomic region represents one of several intergenic enhancers, known as Greek islands, which aggregate to form an interchromosomal hub that enables expression of a single olfactory receptor (OR) gene in olfactory sensory neurons. While all of the other OR gene clusters are sequestered in a large heterochromatic domain, this multi-enhancer interaction network evades heterochromatic silencing by associating with the transcription factors Lhx2 (LIM homeobox 2) and Ebf (EBF transcription factor), which bind in a functionally cooperative manner to allow expression of the active OR gene. The Greek island represented in this genomic region, Tinos, was validated as a functional enhancer by reporter assays in olfactory sensory neurons of transgenic zebrafish embryos.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
