Xenobiotic responsive element gene transcriptions
Associate Editor(s)-in-Chief: Henry A. Hoff
The classical recognition motif of the AhR/ARNT complex, referred to as either the AhR-, dioxin- or xenobiotic- responsive element (AHRE, DRE or XRE), contains the core sequence 5'-GCGTG-3'[1] within the consensus sequence 5'-T/GNGCGTGA/CG/CA-3'[2][3] in the promoter region of AhR responsive genes. The AhR/ARNT heterodimer directly binds the AHRE/DRE/XRE core sequence in an asymmetric manner such that ARNT binds to 5'-GTG-3' and AhR binding 5'-TC/TGC-3'.[4][5][6] Recent research suggests that a second type of element termed AHRE-II, 5'-CATG(N6)C[T/A]TG-3', is capable of indirectly acting with the AhR/ARNT complex.[7][8]

Consensus sequences
(G/T)NGCGTG(A/C)(C/G)A is the consensus sequence for AHRE, DRE or XRE.[2][3]
CATGN6C(A/T)TG is the consensus sequence for AHRE-II.[7][8]

Hypotheses
- A1BG has no regulatory elements in either promoter.
- A1BG is not transcribed by a regulatory element.
- No regulatory element participates in the transcription of A1BG.
AHRE-II samplings
Copying a responsive elements consensus sequence CATGN6C(A/T)TG and putting the sequence in "⌘F" finds none between ZNF497 and A1BG or none between ZSCAN22 and A1BG as can be found by the computer programs.
For the Basic programs testing consensus sequence CATGN6C(A/T)TG (starting with SuccessablesAHREII.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 CATGN6C(A/T)TG, 0.
- positive strand, negative direction, looking for CATGN6C(A/T)TG, 1, CATGGTGGCTCATG at 4116.
- positive strand, positive direction, looking for CATGN6C(A/T)TG, 0.
- negative strand, positive direction, looking for CATGN6C(A/T)TG, 0.
- complement, negative strand, negative direction, looking for GTACN6G(A/T)AC, 1, GTACCACCGAGTAC at 4116.
- complement, positive strand, negative direction, looking for GTACN6G(A/T)AC, 0.
- complement, positive strand, positive direction, looking for GTACN6G(A/T)AC, 0.
- complement, negative strand, positive direction, looking for GTACN6G(A/T)AC, 0.
- inverse complement, negative strand, negative direction, looking for CA(A/T)GN6CATG, 0.
- inverse complement, positive strand, negative direction, looking for CA(A/T)GN6CATG, 1, CATGGTGGCTCATG at 4116.
- inverse complement, positive strand, positive direction, looking for CA(A/T)GN6CATG, 0.
- inverse complement, negative strand, positive direction, looking for CA(A/T)GN6CATG, 0.
- inverse negative strand, negative direction, looking for GT(A/T)CN6GTAC, 1, GTACCACCGAGTAC at 4116.
- inverse positive strand, negative direction, looking for GT(A/T)CN6GTAC, 0.
- inverse positive strand, positive direction, looking for GT(A/T)CN6GTAC, 0.
