Unfolded protein response element gene transcriptions
X-box binding protein 1s "XBP1s binds to the  UPR element (UPRE) containing the consensus sequence TGACGTGG/A and regulates the transcription of target genes in a cell type- and condition-specific manner (Yamamoto et al., 2004)."

# Human genes

# Consensus sequences
The consensus sequence for UPRE is 5'-TGACGTG(G/A)-3'.

# UPRE samplings
Copying the consensus UPRE: TGACGTG(G/A) and putting the sequence in "F" finds no locations between ZNF497 and A1BG or between ZSCAN22 and A1BG as can be found by the computer programs.
For the Basic programs testing consensus sequence TGACGTG(G/A) (starting with SuccessablesUPR.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 TGACGTG(G/A), 4, TGACGTGA at 4340, TGACGTGG at 2761, TGACGTGA at 2426, TGACGTGA at 2000.

# UPRE analysis and results
X-box binding protein 1s "XBP1s binds to the  UPR element (UPRE) containing the consensus sequence TGACGTGG/A and regulates the transcription of target genes in a cell type- and condition-specific manner (Yamamoto et al., 2004)."
Comparison:
The occurrences of real UPREs are larger than the randoms. This suggests that the real UPREs are likely active or activable.
