Glucocorticoid response element gene transcriptions

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

"DNA-binding by the GR-DBD has been well-characterized; it is highly sequence-specific, directly recognizing invariant guanine nucleotides of two AGAACA [TGTTCT] half sites called the glucocorticoid response element (GRE), and binds as a dimer in head-to-head orientation with mid-nanomolar affinity (4,12–18). [...] The consensus DNA glucocorticoid response element (GRE) is comprised of two half-sites (AGAACA) separated by a three base-pair spacer (13,15,60,61)."[1]

Consensus sequences

Hypotheses

  1. A1BG has no GREs in either promoter.
  2. A1BG is not transcribed by a GRE.
  3. A GRE does not participate in the transcription of A1BG.

Glu samplings

Copying an apparent consensus sequence of AGAACA and putting it in "⌘F" finds one located between ZSCAN22 and A1BG and two between ZNF497 and A1BG as can be found by the computer programs.

For the Basic programs testing consensus sequence AGAACA (starting with SuccessablesGlu.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 AGAACA, 1, AGAACA at 281.
  2. positive strand, negative direction, looking for AGAACA, 2, AGAACA at 3668, AGAACA at 287.
  3. negative strand, positive direction, looking for AGAACA, 2, AGAACA at 4068, AGAACA at 3094.
  4. positive strand, positive direction, looking for AGAACA, 0.
  5. inverse complement, negative strand, negative direction, looking for TGTTCT, 4, TGTTCT at 3759, TGTTCT at 3635, TGTTCT at 3340, TGTTCT at 3307.
  6. inverse complement, positive strand, negative direction, looking for TGTTCT, 1, TGTTCT at 45.

Comparison:

The occurrences of real Glucocorticoid UTRs, proximals and distals are greater than the randoms. This suggests that the real Glucocorticoid response elements are likely active or activable.

Pathways

Stimulation of the pathway gluconeogenesis, in particular, in the liver results in the synthesis of glucose from non-hexose substrates, such as amino acids and glycerol from triglyceride breakdown, and is particularly important in carnivores and certain herbivores.
