"The 24-nt Xenopus Mos [polyadenylation response element] PRE (Charlesworth et al, 2002) contained a match to the SELEX-derived murine Musashi RNA binding consensus sequence (G/AU1−3AGU) (Imai et al, 2001), and included a 3′ U residue essential for PRE function (Charlesworth et al, 2002) [...]."[1]

"Regarding the 3′ UTR cis-regulatory sequences such as AREs (PAS) [110], BRD-Box [111] and MBE [112] mediates negative post-transcriptional regulation by affecting mRNA transcript stability and translational efficiency [110], [140]. In our case, the 3′ cis-regulatory signals, BRD-Box and MBE, located upstream and downstream PAS [...] may regulate tissue-specific alternative polyadenylation which has been detected in approximately 54% of human genes [142]."[2]

Consensus sequences

"The [Musashi-binding element] MBE consensus sequence is (G/A)U1–3AGU."[3]

"Musashi did not form a complex with the Mos UTR when the Musashi binding site was disrupted (AUAGU to AUccU [...])."[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.

MBE samplings

Copying a responsive elements consensus sequence (A/G)T1–3AGT and putting the sequenceS in "⌘F" GTAGT, GTTAGT, GTTTAGT finds none or three, or ATTTAGT finds one to three between ZNF497 and A1BG or GTAGT three to six, GTTAGT, GTTTAGT or none between ZSCAN22 and A1BG, or ATAGT none, ATTAGT one, ATTTAGT none as can be found by the computer programs.

For the Basic programs testing consensus sequence (A/G)TAGT (starting with SuccessablesMBE1.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 (A/G)TAGT, 8, GTAGT at 3616, GTAGT at 3521, GTAGT at 3418, GTAGT at 3415, GTAGT at 3394, GTAGT at 2944, GTAGT at 2941, GTAGT at 2888.
  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. inverse complement, negative strand, negative direction, looking for ACTA(C/T), 0.
  6. inverse complement, positive strand, negative direction, looking for TTTTTTTT, 0.
  7. inverse complement, positive strand, positive direction, looking for TTTTTTTT, 0.
  8. inverse complement, negative strand, positive direction, looking for TTTTTTTT, 0.

For the Basic programs testing consensus sequence (A/G)TTAGT (starting with SuccessablesMBE2.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 (A/G)TTAGT, 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. inverse complement, negative strand, negative direction, looking for ACTAA(C/T), 0.
  6. inverse complement, positive strand, negative direction, looking for TTTTTTTT, 0.
  7. inverse complement, positive strand, positive direction, looking for TTTTTTTT, 0.
  8. inverse complement, negative strand, positive direction, looking for TTTTTTTT, 0.

For the Basic programs testing consensus sequence (A/G)TTTAGT (starting with SuccessablesMBE3.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 (A/G)TTTAGT, 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. inverse complement, negative strand, negative direction, looking for ACTAAA(C/T), 0.
  6. inverse complement, positive strand, negative direction, looking for TTTTTTTT, 0.
  7. inverse complement, positive strand, positive direction, looking for TTTTTTTT, 0.
  8. inverse complement, negative strand, positive direction, looking for TTTTTTTT, 0.
