"Functional analyses of a number of hydrolase gene promoters, induced by gibberellin (GA) in aleurone cells following germination, have identified a GA-responsive complex as a tripartite element containing a pyrimidine box motif 5′-CCTTTT-3′."
"Although this GARC [GA responsive complex] may not always be tripartite, most often it includes three sequence motifs, the TAACAAA box or GA responsive element (GARE), the pyrimidine box CCTTTT, and the TATCCAC box (Skriver et al., 1991;Gubler and Jacobsen, 1992; Rogers et al., 1994)."
The "complementary strand of the pyrimidine box element (5′-CTTTT-3′) in GA-induced hydrolase gene promoters was identical to the core sequence (5′-AAAAG-3′) recognized by PBF in prolamin gene promoters (P-box: 5′-T/AAAAG-3′; Vicente-Carbajosa et al., 1997; Mena et al., 1998; Yanagisawa and Schmidt, 1999)".
"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."
"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). 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)."
V and P boxes
"As VRI [target gene: vrille (VRI)] accumulates in the nucleus during the mid to late day, it binds VRI/PDP1ϵ binding sites (V/P-boxes) [consensus A(/G)TTA(/T)T(/C):GTAAT(/C)], to repress Clk and cry transcription (Hardin, 2004)."
"REV-ERBα and RORa are nuclear receptors rather than bZIP transcription factors like VRI and PDP1ϵ, and they regulate transcription by binding RORE elements rather than V/P-boxes (Bell-Pedersen et al., 2005)."
P box consensus sequence is 3'-GTAA(T/C)-5'.
