The SRE wild type (SREwt) contains the nucleotide sequence ACAGGATGTCCATATTAGGACATCTGC, of which CCATATTAGG is the CArG box, TTAGGACAT is the C/EBP box, and CATCTG is the E box.[1]

"Serum response factor (SRF) is an important transcription factor that regulates cardiac and skeletal muscle genes during development, maturation and adult aging [17,18]. SRF regulates its target genes by binding to serum response elements (SREs), which contain a consensus CC(A/T)6GG (CArG) motif."[2]

"The “CCATAATAGG” sequence in the SIRT2 gene promoter is a classic SRE, which allows the SRF dimer to firmly bind to the DNA sequence, whereupon various SRF-binding proteins may be recruited to form a protein complex, which in turn modulates the expression of the SIRT2 gene."[2]

Consensus sequences

In the nucleotide sequence ACAGGATGTCCATATTAGGACATCTGC,

5'-CCATATTAGG-3' is a CArG box that does not occur in either promoter of A1BG,

5'-CATCTG-3' is an E box that does not occur in either promoter of A1BG,

5'-TTAGGACAT-3' is a C/EBP box that does not occur in either promoter of A1BG using "⌘F",

5'-ACAGGATGT-3' is contained in the above nucleotide sequence which has one occurring between ZNF497 and A1BG using "⌘F" and none between ZSCAN22 and A1BG.

SER samplings

Copying a responsive elements consensus sequence ACAGGATGT 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 ACAGGATGT (starting with SuccessablesSER.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.
