Hac1p gene transcriptions
"The  UPR has been shown to play important roles in overexpression and secretion of some recombinant proteins . Manipulating the level of transcription factors and  ER chaperones in the UPR pathway improved secretion of recombinant proteins . An important characteristic of the UPR is that it is directly linked to transcription activation processes governed by ER stress conditions. In Sachcharomyces cerevisiae this process is mediated by a unique mechanism involving cooperative action of Hac1 transcription factor (TF) and a short conserved DNA sequence referred to as unfolded protein response element (UPRE) in the promoter of UPR target genes . The UPRE regulatory cis acting element lies within 22-bp upstream of the promoter of UPR responsive genes, which is crucial for transcriptional induction under ER stress . The best characterized UPRE core sequence was UPRE-1 (CANCNTG) from S. cerevisiae (for examples from KAR2, CAGCGTG and PDI1, CACCGTG) . The similar UPRE-1 is also found in the promoter region of the P. pastoris KAR2 (CAGCGTG), INO1 (CAACTTG) and HAC1 (CAACTTG) genes . The presence of an HAC1 UPRE implies that Hac1p can up-regulate its own transcription. Unconventional splicing of HAC1 mRNA after ER stress signaling generates the active form of basic leucine zipper (bZIP) transcription factor Hac1p, which binds to the UPRE ."

# Human genes

# Consensus sequences
The upstream activating sequence (UAS) for Hac1p is 5'-CAGCGTG-3'.

# KAR2 samplings
Copying 5'-CAGCGTG-3' in "F" yields none between ZSCAN22 and A1BG and none between ZNF497 and A1BG as can be found by the computer programs.

The upstream activating sequence (UAS) for Hac1p is CAGCGTG.
Comparison:
The occurrences of real KAR2 distals are greater than the randoms. This suggests that the real KAR2s are likely active or activable.
