"The activity of the native TRX2 promoter, which is regulated by the transcription factor Yap1p, can be altered by sensing NADPH/NADP+ ratios, but its sensitivity is low. Increasing the number of the UAS-containing Yap1p binding sites greatly enhanced the cascade response effect, and this novel biosensor was useful at selecting cell populations with higher NADPH/NADP+ ratios [139]."[1]

"Saccharomyces cerevisiae contains eight members of a novel and fungus-specific family of bZIP proteins that is defined by four atypical residues on the DNA-binding surface. Two of these proteins, Yap1 and Yap2, are transcriptional activators involved in pleiotropic drug resistance. Although initially described as AP-1 factors, at least four Yap proteins bind most efficiently to TTACTAA, a sequence that differs at position ±2 from the optimal AP-1 site (TGACTCA); further, a Yap-like derivative of the AP-1 factor Gcn4 (A239Q S242F) binds efficiently to the Yap recognition sequence."[2]

Interactions

Consensus sequences

The upstream activating sequence (UAS) for Yap1p/2p is TTACTAA, which is found in genes GSH1, TRX2, YCF1, GLR1, induced by oxidative stress such as H2O2, for regulation of genes expressed in response to environmental changes.[1]

Yap samplings

Copying TTACTAA 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 AAAAAAAA (starting with SuccessablesAAA.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:

  1. negative strand, negative direction, looking for AAAAAAAA, 0.
  2. positive strand, negative direction, looking for AAAAAAAA, 0.
  3. positive strand, positive direction, looking for AAAAAAAA, 0.
  4. negative strand, positive direction, looking for AAAAAAAA, 0.
  5. complement, negative strand, negative direction, looking for TTTTTTTT, 0.
  6. complement, positive strand, negative direction, looking for TTTTTTTT, 0.
  7. complement, positive strand, positive direction, looking for TTTTTTTT, 0.
  8. complement, negative strand, positive direction, looking for TTTTTTTT, 0.
  9. inverse complement, negative strand, negative direction, looking for TTTTTTTT, 0.
  10. inverse complement, positive strand, negative direction, looking for TTTTTTTT, 0.
  11. inverse complement, positive strand, positive direction, looking for TTTTTTTT, 0.
  12. inverse complement, negative strand, positive direction, looking for TTTTTTTT, 0.
  13. inverse negative strand, negative direction, looking for AAAAAAAA, 0.
  14. inverse positive strand, negative direction, looking for AAAAAAAA, 0.
  15. inverse positive strand, positive direction, looking for AAAAAAAA, 0.
  16. inverse negative strand, positive direction, looking for AAAAAAAA, 0.
