Gcn4p gene transcriptions
Associate Editor(s)-in-Chief: Henry A. Hoff
"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.
For the Basic programs testing consensus sequence ATGACTCTT (starting with SuccessablesGcn4.bas) written to compare nucleotide sequences with the sequences on either the template strand (-), or coding strand (+), of the DNA, in the negative direction (-), or the positive direction (+), the programs are, are looking for, and found:
- negative strand, negative direction, looking for ATGACTCTT, 0.
- negative strand, positive direction, looking for ATGACTCTT, 0.
- positive strand, negative direction, looking for ATGACTCTT, 0.
