Regulation and epigenetic control of transcription at the nuclear periphery

Trends Genet. 2007 Aug;23(8):396-402. doi: 10.1016/j.tig.2007.05.009. Epub 2007 Jun 12.


The localization of DNA within the nucleus influences the regulation of gene transcription. Subnuclear environments at the nuclear periphery promote gene silencing and activation. Silenced regions of the genome, such as centromeres and telomeres, are statically tethered to the nuclear envelope. Recent work in yeast has revealed that certain genes can undergo dynamic recruitment to the periphery upon transcriptional activation. For such genes, localization to the periphery has been suggested to improve mRNA export and favor optimal transcription. In addition, maintenance of peripheral localization confers cellular memory of previous transcriptional activation, enabling cells to adapt rapidly to transcriptional cues.
