Artificial repressors for controlling gene expression in bacteria

Chem Commun (Camb). 2013 May 14;49(39):4325-7. doi: 10.1039/c2cc37107c. Epub 2012 Dec 10.

Abstract

Transcriptional repression is a common approach to control gene expression in synthetic biology applications. Here, an engineered DNA binding protein based upon a transcription activator-like effector (TALE) scaffold was shown to outperform LacI in blocking transcription from a promoter and to repress expression of a downstream gene in an operon.
