X-box binding protein 1s "XBP1s binds to the [unfolded protein response] 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)."[1]

Human genes

Consensus sequences

The consensus sequence for UPRE is 5'-TGACGTG(G/A)-3'.[1]

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:

  1. negative strand, negative direction, looking for TGACGTG(G/A), 4, TGACGTGA at 4340, TGACGTGG at 2761, TGACGTGA at 2426, TGACGTGA at 2000.

Comparison:

The occurrences of real UPREs are larger than the randoms. This suggests that the real UPREs are likely active or activable.
