"The BPBF [barley prolamin-box (P-box) binding factor] expressed in bacteria as a GST-fusion binds a P-box 5′-TGTAAAG-3′ containing oligonucleotide derived from the promoter region of anHor2gene."[1]

"The primary structure of hordein [barley prolamins] polypeptides is closely related to that of prolamins from other grass species from the Pooideae subfamily, such as wheat and rye (Shewry & Tatham 1990;Shewry et al. 1995)."[1]

Consensus sequences

"The close evolutionary relationship is also manifested by the conservation of a putative regulatory element in their gene promoters, the endosperm box (Forde et al. 1985;Kreis et al. 1985). This conserved region consists of two motifs, a 7 bp element (5′TGTAAAG3′) termed the Prolamin Box (P-box) or endosperm motif (EM) followed at a distance of up to 8 nucleotides by the GCN4-like motif (GLM) which has the 5′(G/A)TGA(G/C)TCA(T/C)3′ consensus sequence (reviewed by Müller et al. 1995)."[1]

"The main cis-element present in their promoters is an endosperm-specific box [19,20], which consists of two motifs: a GLM (GCN4-like motif) (5′ G(A)TGA(G) GTCAT 3′) that shares homology with yeast GCN4 [21], and a 7 bp P-box (Prolamin box) (5′TGTAAAG3′) [22–24]."[2]

Prolamin box sampling

For the Basic programs (starting with SuccessablesProl.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 in the negative direction (from ZSCAN22 to A1BG) is SuccessablesProl--.bas, looking for TG(A/T)AAAG, 1, TGTAAAG-5 at 2884,
  2. negative strand in the positive direction (from ZNF497 to A1BG) is SuccessablesProl-+.bas, looking for TG(A/T)AAAG, 1, TGAAAAG at 3928,
  3. positive strand in the negative direction is SuccessablesProl+-.bas, looking for TG(A/T)AAAG, 1, TGAAAAG at 1627,
  4. positive strand in the positive direction is SuccessablesProl++.bas, looking for TG(A/T)AAAG, 1, TGAAAAG at 2275, and complement.
  5. complement, negative strand, negative direction is SuccessablesProlc--.bas, looking for AC(A/T)TTTC, 1, ACTTTTC at 1627,
  6. complement, negative strand, positive direction is SuccessablesProlc-+.bas, looking for AC(A/T)TTTC, ACTTTC at 3928,
  7. complement, positive strand, negative direction is SuccessablesProlc+-.bas, looking for AC(A/T)TTTC, 1, ACATTTC at 2884,
  8. complement, positive strand, positive direction is SuccessablesProlc++.bas, looking for AC(A/T)TTTC, 1, ACTTTTC at 3928,
  9. inverse complement, negative strand, negative direction is SuccessablesProlci--.bas, looking for CTTT(A/T)CA, 0,
  10. inverse complement, negative strand, positive direction is SuccessablesProlci-+.bas, looking for CTTT(A/T)CA, 0,
  11. inverse complement, positive strand, negative direction is SuccessablesProlci+-.bas, looking for CTTT(A/T)CA, 0,
  12. inverse complement, positive strand, positive direction is SuccessablesProlci++.bas, looking for CTTT(A/T)CA, 0,
  13. inverse, negative strand, negative direction, is SuccessablesProli--.bas, looking for GAAA(A/T)GT, 0,
  14. inverse, negative strand, positive direction, is SuccessablesProli-+.bas, looking for GAAA(A/T)GT, 0,
  15. inverse, positive strand, negative direction, is SuccessablesProli+-.bas, looking for GAAA(A/T)GT, 0,
  16. inverse, positive strand, positive direction, is SuccessablesProli++.bas, looking for GAAA(A/T)GT, 0.
