Comparison:
The occurrences of real GCN4 UTRs, cores, proximals and positive direction distals are greater than the randoms and the negative direction distals are outside the randoms. This suggests that the real GCN4s are likely active or activable.

"The saturation mutagenesis of the transcription factor [general control nonderepressible gene protein] 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 (Tang)

UAS Sequence for the transcription factor Gcn4p binding site is ATGACTCTT.[1]

Copying ATGACTC in "⌘F" yields none between ZNF497 and A1BG on the negative strand.

Copying ATGACTCT in "⌘F" yields none between ZNF497 and A1BG on the positive strand.

Copying ATGACTCA in "⌘F" yields none between ZNF497 and A1BG on the positive strand.

Copying ATGACTC in "⌘F" yields none between ZSCAN22 and A1BG on the negative strand.

Copying ATGACTCTT in "⌘F" yields none between ZSCAN22 and A1BG on the positive strand.

Copying ATGACTCA in "⌘F" yields none between ZSCAN22 and A1BG on the positive strand.

Copying ATGACTC(A/T)T in "⌘F" yields none between ZSCAN22 and A1BG and none between ZNF497 and A1BG as can be found by the computer programs:

Comparison:

The occurrences of real GCN4 UTRs, cores, proximals and positive direction distals are greater than the randoms and the negative direction distals are outside the randoms. This suggests that the real GCN4s are likely active or activable.
