Nucleosome Position-Dependent and -Independent Activation of HIS7 Expression in Saccharomyces cerevisiae by Different Transcriptional Activators
... The chromatin of the noninduced HIS7-promoter is an ac- cessible open one, sustaining weak HIS7 expression (Fig. 7). This open structure is compatible with the Bas1p/Bas2p-medi- ated HIS7 activation during adenine ...

Activation of a heterologous promoter by human immunodeficiency virus type 1 Tat requires Sp1 and is distinct from the mode of activation by acidic transcriptional activators.
... To test whether Tat could function as a typical transcriptional activator, we previously targeted a Gal-Tat fusion protein upstream of a synthetic promoter via Gal binding sites and were[r] ...
