Associate Editor(s)-in-Chief: Henry A. Hoff

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 (C/G)C(G/T)NNNN(A/C)G(C/G) (starting with SuccessablesLeu.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:
