With HAS1 ending at zero and TDA1 beginning at above 1000 bp, Leu3 is from 536 - 545 nts yielding consensus sequences (C/G)C(G/T)NNNN(A/C)G(C/G), 569 - 574 Mig1 (C/T)(C/T)CC(A/G)G and Sdd4 (A/C/T)CCCAC, 585 - 592 Rgt1 (A/T)(A/T)N(A/T)(C/T)CCG, 610 - 617 Rgt1 (A/T)(A/T)N(A/T)(C/T)CCG, 630 - 637 Rgt CGG(A/G)(A/T)N(A/T)(A/T).[1]

"Leu3, a well-known transcription factor of genes involved in the metabolism of branched amino acids [13], also has a negative effect on UGA4 and UGA1 expression but does not affect UGA2 expression [10, 11, 14]. Even though Leu3 could not be detected bound to the UGA4 promoter, it interferes in the interaction of Dal81 but not of Uga3 with the UGA4 promoter [11]. The transcription factors Uga3, Dal81 and Leu3 belong to the class III family (Zn(II)2Cys6 proteins), and they recognize highly related sequences rich in GGC triplets [15]."[2]

Gene expressions

Interactions

"Although there is a putative consensus site for Leu3 within the UASGABA element of UGA4 and UGA1 genes, we were not able to detect any interaction between Leu3 and the UGA4 promoter [11]."[2]

Consensus sequences

Leu3 is from 536 - 545 nts yielding consensus sequences (C/G)C(G/T)NNNN(A/C)G(C/G).[1]

Binding site for

Complement copies

Inverse copies

Complement-inverse copies

Enhancer activity

Promoter occurrences

"The regulatory regions of the UGA4 and UGA1 genes contain a UASGABA element (5′-AAAAACCGCCGGCGGCAAT-3′) target of Uga3 and Dal81 factors. Within this element there is a consensus site [CCGCCGGCGG] for Leu3 [8, 10, 11, 35]."[2]

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.

Leu samplings

Copying a responsive elements consensus sequence (C/G)C(G/T)NNNN(A/C)G(C/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 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.
