"Vhr1p [is] a transcriptional regulator of VHT1 (VHR1 (YIL056w)".[1]

Human genes

Gene expressions

Vhr1p upstream activator sequence (UAS) occurs in the promoters of VHT1, BIO5 Saccharomyces cerevisiae genes.[2] Its inducer is biotin where it responds to low biotin concentrations.[2]

Interactions

Consensus sequences

AATCA-N8-TGA(C/T)T is the UAS sequence for the transcription factor Vhr1p.[2]

Binding site for

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.

VHR samplings

Copying a responsive elements consensus sequence AATCA-N8-TGA(C/T)T 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 AATCA-N8-TGA(C/T)T (starting with SuccessablesVHR.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 AATCANNNNNNNNTGA(C/T)T, 0.
  2. positive strand, negative direction, looking for AATCANNNNNNNNTGA(C/T)T, 0.
  3. positive strand, positive direction, looking for AATCANNNNNNNNTGA(C/T)T, 0.
  4. negative strand, positive direction, looking for AATCANNNNNNNNTGA(C/T)T, 0.
  5. complement, negative strand, negative direction, looking for TTAGTNNNNNNNNACT(A/G)A, 0.
  6. complement, positive strand, negative direction, looking for TTAGTNNNNNNNNACT(A/G)A, 0.
  7. complement, positive strand, positive direction, looking for TTAGTNNNNNNNNACT(A/G)A, 0.
  8. complement, negative strand, positive direction, looking for TTAGTNNNNNNNNACT(A/G)A, 0.
  9. inverse complement, negative strand, negative direction, looking for A(A/G)TCANNNNNNNNTGATT, 0.
  10. inverse complement, positive strand, negative direction, looking for A(A/G)TCANNNNNNNNTGATT, 0.
  11. inverse complement, positive strand, positive direction, looking for A(A/G)TCANNNNNNNNTGATT, 0.
