"The saturation mutagenesis of the transcription factor Gcn4p’s binding site (5′-ATGACTCTT-3′) within the HIS3 promoter found that almost all mismatch mutants reduced the PHIS3 activity significantly and only one mutant with the sequence 5′-ATGACTCAT-3′ increased the binding affinity of Gcn4p and improved the PHIS3 activity [82]. It has been shown that regulatory regions containing multiple UAS or URS sites for binding the same transcription factor could enhance their activation or repression of transcription. In a test of 15 transcription factors, such as Gal4p, Gcn4p, Bas1p, increasing the number of their UAS sites improved promoter activities; similarly, promoters with multiple URS sites showed a stronger repression, such as Matα2p-Mcm1p."[1]

Human genes

Interactions

The "transcription factor Rap1p not only depleted the nucleosome from its own binding site of the HIS4 promoter, but also reduced a nearby nucleosome to increase the accessibility of other transcription factors, including Gcn4p, Bas1p, Bas2p [102]."[1]

Consensus sequences

UAS Sequence for the transcription factor Gcn4p is 5'-ATGACTCTT-3'.[1]

Samplings

Copying 5'-ATGACTCTT-3' in "⌘F" yields none between ZSCAN22 and A1BG and none between ZNF497 and A1BG as can be found by the computer programs.
