"The most well-understood mechanism for controlling cytoplasmic polyadenylation is regulation of mRNAs containing the cytoplasmic polyadenylation element (CPE; consensus UUUUUAU) by CPE-binding protein (CPEB)1."[1]

Human genes

CPEB1

Gene expressions

Interactions

Consensus sequences

"Cytoplasmic polyadenylation is determined by the cytoplasmic polyadenylation element (CPE; consensus sequence UUUUUAU) that resides in mRNA 3′ untranslated regions (UTRs)."[2]

"CPE: cytoplasmic polyadenylation element [consensus (U)4–5(A)1-2U]".[1]

Binding site for

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.

CPE samplings

Copying a responsive elements consensus sequence AAAAAAAA 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 AAAAAAAA (starting with SuccessablesAAA.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 AAAAAAAA, 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. complement, negative strand, negative direction, looking for TTTTTTTT, 0.
  6. complement, positive strand, negative direction, looking for TTTTTTTT, 0.
  7. complement, positive strand, positive direction, looking for TTTTTTTT, 0.
  8. complement, negative strand, positive direction, looking for TTTTTTTT, 0.
  9. inverse complement, negative strand, negative direction, looking for TTTTTTTT, 0.
  10. inverse complement, positive strand, negative direction, looking for TTTTTTTT, 0.
  11. inverse complement, positive strand, positive direction, looking for TTTTTTTT, 0.
  12. inverse complement, negative strand, positive direction, looking for TTTTTTTT, 0.
  13. inverse negative strand, negative direction, looking for AAAAAAAA, 0.
  14. inverse positive strand, negative direction, looking for AAAAAAAA, 0.
  15. inverse positive strand, positive direction, looking for AAAAAAAA, 0.
  16. inverse negative strand, positive direction, looking for AAAAAAAA, 0.
