"In vitro DNA binding assays associate [Ethylene Response Factor] ERF family members with GCC-box motifs (5’-AGCCGCC-3’) (Ohme-Takagi and Shinshi, 1995; Hao et al., 1998), which have been traced out in many genes induced by ethylene, pathogenesis, wounding, or jasmonate (Brown et al., 2003; Zarei et al., 2011)."[1]

Human genes

Consensus sequences

Ethylene responsive elements (ATTTCAAA).[2]

Hypotheses

  1. A1BG has no ethylene responsive elements in either promoter.
  2. A1BG is not transcribed by an ethylene responsive element.
  3. An ethylene responsive element does not participate in the transcription of A1BG.

ERE samplings

Copying an apparent consensus sequence of ATTTCAAA and putting it in "⌘F" finds none located between ZSCAN22 and A1BG and one between ZNF497 and A1BG as can be found by the computer programs.

For the Basic programs testing consensus sequence ATTTCAAA (starting with SuccessablesEth.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 5'-ATTTCAAA-3', 0.
  2. negative strand, positive direction, looking for 5'-ATTTCAAA-3', 1, ATTTCAAA at 2648.
  3. positive strand, negative direction, looking for 5'-ATTTCAAA-3', 1, ATTTCAAA at 1383.
  4. positive strand, positive direction, looking for 5'-ATTTCAAA-3', 0.
  5. complement, negative strand, negative direction, looking for 5'-TAAAGTTT-3', 1, 5'-TAAAGTTT-3' at 1383.
  6. complement, negative strand, positive direction, looking for 5'-TAAAGTTT-3', 0.
  7. complement, positive strand, negative direction, looking for 5'-TAAAGTTT-3', 0.
  8. complement, positive strand, positive direction, looking for 5'-TAAAGTTT-3', 1, 5'-TAAAGTTT-3' at 2648.
  9. inverse complement, negative strand, negative direction, looking for 5'-TTTGAAAT-3', 0.
  10. inverse complement, negative strand, positive direction, looking for 5'-TTTGAAAT-3', 0.
  11. inverse complement, positive strand, negative direction, looking for 5'-TTTGAAAT-3', 0.
  12. inverse complement, positive strand, positive direction, looking for 5'-TTTGAAAT-3', 0.
  13. inverse negative strand, negative direction, looking for 5'-AAACTTTA-3', 0.
  14. inverse negative strand, positive direction, looking for 5'-AAACTTTA-3', 0.
  15. inverse positive strand, negative direction, looking for 5'-AAACTTTA-3', 0.
  16. inverse positive strand, positive direction, looking for 5'-AAACTTTA-3', 0.

Comparison:

The occurrences of real ethylene responsive element consensus sequences are larger than the randoms. This suggests that the ethylene responsive element consensus sequences are likely active or activable.
