Yap1p,2p gene transcriptions
"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 ."
"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."

# Human genes

# 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.

# 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.

# Yap analysis and results
At "least four Yap proteins bind most efficiently to TTACTAA, a sequence that differs at position 2 from the optimal AP-1 site (TGACTCA)".
Comparison:
The occurrences of real Yap UTRs are greater than the randoms. This suggests that the real Yaps are likely active or activable.

# YapR analysis and results
"Yap1p recognizes YRE (Yap1p response elements, 5'-TKACTMA-3') in the promoters of genes involved in redox homeostasis and in xenobiotic export at the plasma membrane."
Comparison:
The occurrences of real YapR UTRs and distals are greater than the randoms. This suggests that the real YapRs are likely active or activable.
