"The basal regulatory elements identified include a putative TATA-box (−30/−24) for RNA polymerase binding and a CAAT box (−64/−61; [...]). Several putative floral expression-related cis-elements identified included a putative 6-nucleotide Q element (−770/−665), three GTGA boxes (−372/−369, −209/−206 and −164/−161) and four putative highly-conserved POLLEN1 boxes (−737/−733, −711/−707, −150/−146 and −36/−32; [...])."[1]

Consensus sequences

The consensus sequence for a Q element is 3'-AGGTCA-5'.[1]

QE samplings

Copying the apparent consensus sequence for the QE (AGGTCA) and putting it in "⌘F" finds two located between ZSCAN22 or three between ZNF497 and A1BG as can be found by the computer programs.

For the Basic programs testing consensus sequence AGGTCA (starting with SuccessablesQE.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:

Comparison: The occurrences of real QE UTRs, cores and distals are greater than the randoms. This suggests that the real QEs are likely active or activable.
