"Human pColQ1a carries consensus sequences for transcriptional factors E-protein (E-box, CANNTG), NFAT (GGAAA), c-Ets transcription factor [c-Ets, (C/A)GGA(A/T)], Elk-1, N-box (CCGGAA), and MEF2 (CTAAAAATAA), which play essential roles in muscle-specific and NMJ-specific transcriptional activities (Lee et al., 2004)."[1]

Binding site for

"The [basic helix–loop–helix] bHLH proteins from group E were usually bound to the CACGCG [Coupling element] or CACGAG (N-box) motif."[2]

"Group E comprises two families in which the proteins have a conserved Pro or Gly residue within the basic region that mediates preferential binding to the N-box sequences CACGGC or CACGAC."[3]

Promoter occurrences

"Transcriptional upregulation of pColQ1a at the [neuromuscular junction] NMJ is mediated by the N-box (CCGGAA; Lee et al., 2004). The N-box (CGGAA) is also the neuregulin-response element in mouse Chrnd encoding the δ subunit of acetylcholine receptor (AChR; Fromm and Burden, 1998) and in rat Chrne encoding the AChR ε subunit (Sapru et al., 1998). Similar involvement of the neuregulin-responsive N-box in the NMJ-specific transcription of ColQ in mouse have also been reported (Lee et al., 2004; Ting et al., 2005). Also, specific activation of pColQ1 and pColQ1a in slow- and fast-twitch muscles, respectively, is mediated by a slow upstream regulatory element (SURE) in pColQ1 and a fast intronic regulatory element (FIRE) in pColQ1a (Lee et al., 2004; Ting et al., 2005)."[1]

Hypotheses

  1. A1BG has no regulatory elements in either promoter.
  2. A1BG is not transcribed by a regulatory element.
  3. No regulatory element participates in the transcription of A1BG.

N-box (Lee) samplings

Copying a responsive elements consensus sequence CCGGAA 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.
