"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

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.

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.
