Consensus sequences

edit

"The comparison of the two rp51 genes [...] suggests that this homology might be more extensive if one allows up to 3 bases to differ from a larger consensus sequence, ATTTACTAAC."[2]

Samplings of the A1BG promoters

edit

For the Basic programs (starting with SuccessablesTACT.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 in the negative direction (from ZSCAN22 to A1BG) is SuccessablesTACT--.bas, looking for 3'-TACTAA(C/T)-5', 0,
  2. negative strand in the positive direction (from ZNF497 to A1BG) is SuccessablesTACT-+.bas, looking for 3'-TACTAA(C/T)-5', 0,
  3. positive strand in the negative direction is SuccessablesTACT+-.bas, looking for 3'-TACTAA(C/T)-5', 0,
  4. positive strand in the positive direction is SuccessablesTACT++.bas, looking for 3'-TACTAA(C/T)-5', 1, 3'-TACTAAT-5', 718,
  5. complement, negative strand, negative direction is SuccessablesTACTc--.bas, looking for 3'-ATGATT(A/G)-5', 0,
  6. complement, negative strand, positive direction is SuccessablesTACTc-+.bas, looking for 3'-ATGATT(A/G)-5', 1, 3'-ATGATTA-5', 718,
  7. complement, positive strand, negative direction is SuccessablesTACTc+-.bas, looking for 3'-ATGATT(A/G)-5', 0,
  8. complement, positive strand, positive direction is SuccessablesTACTc++.bas, looking for 3'-ATGATT(A/G)-5', 0,
  9. inverse complement, negative strand, negative direction is SuccessablesTACTci--.bas, looking for 3'-(A/G)TTAGTA-5', 0,
  10. inverse complement, negative strand, positive direction is SuccessablesTACTci-+.bas, looking for 3'-(A/G)TTAGTA-5', 0,
  11. inverse complement, positive strand, negative direction is SuccessablesTACTci+-.bas, looking for 3'-(A/G)TTAGTA-5', 0,
  12. inverse complement, positive strand, positive direction is SuccessablesTACTci++.bas, looking for 3'-(A/G)TTAGTA-5', 1, 3'-ATTAGTA-5', 709,
  13. inverse, negative strand, negative direction, is SuccessablesTACTi--.bas, looking for 3'-(C/T)AATCAT-5', 0,
  14. inverse, negative strand, positive direction, is SuccessablesTACTi-+.bas, looking for 3'-(C/T)AATCAT-5', 1, 3'-TAATCAT-5', 709,
  15. inverse, positive strand, negative direction, is SuccessablesTACTi+-.bas, looking for 3'-(C/T)AATCAT-5', 0,
  16. inverse, positive strand, positive direction, is SuccessablesTACTi++.bas, looking for 3'-(C/T)AATCAT-5', 0.
