... amplifying gene expression. Notably, the binding of the PIC to the TATA box and the binding of transcription factors to other sites could be cooperative [44]. This would make the effect of the TATA ... underlying these differences, and how they may contribute to the evolvability of gene expression. Yeast is an excellent model for studying the evolution...

... specify ESEs. The issue of gene location gets to the heart of the relationship between genome organization and the control of gene expression. The simplest model supposes that a gene with its ... gene can potentially influence, by accident, the expression of neighboring genes. Indeed, the transcription rate of a transgene corresponds to that of the genes...
