The MexAB-OprM drug efflux pump is central to multidrug resistance of Pseudomonas aeruginosa. The ability of the tripartite protein to confer drug resistance on the pathogen is crucially dependent on the presence of all three proteins of the complex. However, the role of each protein in the formation of the intact functional complex is not well understood.… (More)

A challenging question in genetics is to understand the molecular function of non-coding variants of the genome. By using differential EMSA, ChIP and functional genome analysis, we have found that changes in transcription factors (TF) apparent binding affinity and dissociation rates are responsible for allele specific assembly or disruption of master TFs:… (More)
