# A1BG has neither a B-box (TGGGCA) nor a box B (or B1 box) (TGTCTCA) in either promoter.
# A1BG is not transcribed by either B box.
# Neither B box participates in the transcription of A1BG.

Copying the above consensus B box and putting the sequences in "⌘F" locates any consensus sequences in any nucleotide positions as may be found by the computer programs.
One 3'-TGGGCA-5' shows up at about -600 nucleotides from the TSS between ZSCAN22 and A1BG as A1BG is approached from ZSCAN22 on the positive strand. This warrants testing with the computer programs.

Comparison:
The occurrences of real B-boxes UTRs, proximals and negative direction distals are greater than the randoms, positive direction distals are greater than or equal to the randoms. This suggests that the real B-boxes are likely active or activable.

"The mP2 EB fragment used for binding was the 118 nucleotide fragment extending from the Dde I site at position -140 to the Dde I site at position -23 [...]. This fragment contains the GC, E, B, CAAT, and TATA boxes."[1]

Consensus sequences

Main article: Consensus sequence gene transcriptions

TGGGCA is a B-box.[1]

"The human [Transforming growth factor b1] TGFB1 promoter region contains two binding sequences for [Activator protein-1] AP-1, designated AP-1 box A (TGACTCT) and box B (TGTCTCA), which mediate the upregulation of promoter activity via a PKC-dependent pathway after exposure of cells to a high-glucose environment (Refs 37, 38)."[2]

Hypotheses

  1. A1BG has neither a B-box (TGGGCA) nor a box B (or B1 box) (TGTCTCA) in either promoter.
  2. A1BG is not transcribed by either B box.
  3. Neither B box participates in the transcription of A1BG.

B box (Johnson) samplings

Copying the above consensus B box and putting the sequences in "⌘F" locates any consensus sequences in any nucleotide positions as may be found by the computer programs.

One 3'-TGGGCA-5' shows up at about -600 nucleotides from the TSS between ZSCAN22 and A1BG as A1BG is approached from ZSCAN22 on the positive strand. This warrants testing with the computer programs.

  1. Negative strand, negative direction: 0.
  2. Positive strand, negative direction: 9, TGGGCA at 4191, TGGGCA at 4040, TGGGCA at 3301, TGGGCA at 2773, TGGGCA at 2438, TGGGCA at 1359, TGGGCA at 1114, TGGGCA at 902, TGGGCA at 462.
  3. Negative strand, positive direction: 4, TGGGCA at 4180, TGGGCA at 2894, TGGGCA at 1945, TGGGCA at 27.
  4. Positive strand, positive direction: 0.
  5. Inverse complement, negative strand, negative direction: 0.
  6. Inverse complement, positive strand, negative direction: 4, TGCCCA at 4251, TGCCCA at 3883, TGCCCA at 3854, TGCCCA at 1458.
  7. Inverse complement, negative strand, positive direction: 2, TGCCCA at 3377, TGCCCA at 3237.
  8. Inverse complement, positive strand, positive direction: 1, TGCCCA at 3750.

Comparison:

The occurrences of real B-boxes UTRs, proximals and negative direction distals are greater than the randoms, positive direction distals are greater than or equal to the randoms. This suggests that the real B-boxes are likely active or activable.

Comparison:

The occurrences of real box Bs are greater than the randoms. This suggests that the real box Bs are likely active or activable.
