Gene regulation: enhancers stepping out of the shadow

Curr Biol. 2010 Sep 14;20(17):R697-9. doi: 10.1016/j.cub.2010.07.035.


The expression of many animal genes has been shown to be controlled by two--rather than one--enhancers with similar regulatory content. Such enhancer redundancy ensures robustness of gene expression under adverse environmental or genetic conditions.
