"The arrangement of TREs within the promoter might regulate THR action by determining THR isoform binding, THR dimerization, and coregulators binding. In the classic view of how TH and its receptor stimulate gene expression, the gene promoter contains TREs consisting of a 6-bp consensus sequence (AGGTCA) organized as a direct repeat separated by 4 bp (DR4), a palindrome without spacing (PAL), or an inverted palindrome (LAP) separated by 4 to 6 bp (10–13)."[1]

Consensus sequences

The "gene promoter contains TREs consisting of a 6-bp consensus sequence (AGGTCA) organized as a direct repeat separated by 4 bp (DR4), a palindrome without spacing (PAL), or an inverted palindrome (LAP) separated by 4 to 6 bp (10–13)."[1]

THR samplings

Copying the consensus sequence for the THR AGGTCA and putting the sequence in "⌘F" finds no locations between ZNF497 and A1BG or two locations between ZSCAN22 and A1BG as can be found by the computer programs.

For the Basic programs testing consensus sequence AGGTCA (starting with SuccessablesTHR.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 AGGTCA, 0.
  2. positive strand, negative direction, looking for AAAAAAAA, 0.
  3. positive strand, positive direction, looking for AAAAAAAA, 0.
  4. negative strand, positive direction, looking for AAAAAAAA, 0.
  5. complement, negative strand, negative direction, looking for TCCAGT, 0.
  6. complement, positive strand, negative direction, looking for TTTTTTTT, 0.
  7. complement, positive strand, positive direction, looking for TTTTTTTT, 0.
  8. complement, negative strand, positive direction, looking for TTTTTTTT, 0.
  9. inverse complement, negative strand, negative direction, looking for TGACCTT, 0.
  10. inverse complement, positive strand, negative direction, looking for TTTTTTTT, 0.
  11. inverse complement, positive strand, positive direction, looking for TTTTTTTT, 0.
  12. inverse complement, negative strand, positive direction, looking for TTTTTTTT, 0.
  13. inverse negative strand, negative direction, looking for ACTGGA, 0.
  14. inverse positive strand, negative direction, looking for AAAAAAAA, 0.
  15. inverse positive strand, positive direction, looking for AAAAAAAA, 0.
  16. inverse negative strand, positive direction, looking for AAAAAAAA, 0.
