"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]."[1]

Human genes

Gene expressions

Interactions

Consensus sequences

"Known consensus string Type of motifs LEU3 CCGNNNNCGG or GGCNNNNGCC Gapped motif".[2]

"MEME analysis identified phylogenetically conserved CCGN4CGG motifs in promoters of several [branched-chain amino acid] BCAA biosynthetic genes"[3]

"The promoters of the BCAA biosynthetic leuA and the iron-regulatory hapX genes contain an evolutionary conserved CCGN4CGG motif."[3]

"LeuB is able to bind to the CCGN4CGG motifs in the promoters of gdhA, hapX and leuA."[3]

Binding site for

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 for Leu3 [8, 10, 11, 35]. In contrast, UGA2 has a consensus site for Uga3 (5'-SGCGGNWTT-3') but not a defined UASGABA element or a Leu3 putative site."[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.

Samplings

Copying a responsive elements consensus sequence AAAAAAAA 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.
