Human genes

Gene expressions

"Mac1p-dependent adaptation to copper deficiency involves the coordinate expression of genes, CTR1, CTR3, FRE1, and FRE7, encoding assimilatory components, through copper-response elements associated with each of these genes (10., 11., 12.)."[1]

The "Cyc6 gene contains at least two copper-response elements (CuREs) (28)."[1]

Interactions

Consensus sequences

"A consensus copper-response element [CuRE] TTTGC(T/G)C(A/G) (12) is a binding site for Mac1p."[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.

CuRE (Quinn) samplings

Copying a responsive elements consensus sequence TTTGC(G/T)C(A/G) 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 TTTGC(G/T)C(A/G) (starting with SuccessablesCuRE.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 TTTGC(G/T)C(A/G), 0.
  2. positive strand, negative direction, looking for TTTGC(G/T)C(A/G), 0.
  3. positive strand, positive direction, looking for TTTGC(G/T)C(A/G), 0.
  4. negative strand, positive direction, looking for TTTGC(G/T)C(A/G), 0.
  5. complement, negative strand, negative direction, looking for AAACG(A/C)G(C/T), 0.
  6. complement, positive strand, negative direction, looking for AAACG(A/C)G(C/T), 0.
  7. complement, positive strand, positive direction, looking for AAACG(A/C)G(C/T), 0.
  8. complement, negative strand, positive direction, looking for AAACG(A/C)G(C/T), 0.
  9. inverse complement, negative strand, negative direction, looking for (C/T)G(A/C)GCAAA, 0.
  10. inverse complement, positive strand, negative direction, looking for (C/T)G(A/C)GCAAA, 1, CGCGCAAA at 163.
  11. inverse complement, positive strand, positive direction, looking for (C/T)G(A/C)GCAAA, 0.
  12. inverse complement, negative strand, positive direction, looking for (C/T)G(A/C)GCAAA, 0.
  13. inverse negative strand, negative direction, looking for (A/G)C(G/T)CGTTT, 1, GCGCGTTT at 163.
  14. inverse positive strand, negative direction, looking for (A/G)C(G/T)CGTTT, 0.
  15. inverse positive strand, positive direction, looking for (A/G)C(G/T)CGTTT, 0.
  16. inverse negative strand, positive direction, looking for (A/G)C(G/T)CGTTT, 0.
