ACGT-containing element gene transcriptions
Associate Editor(s)-in-Chief: Henry A. Hoff
The "binding affinities of both bZIP proteins were similar to CREA/T (ATGACGTCAT), a CRE sequence with flanking adenine and thymine (A/T) at positions -4 and +4. [The] bZIP domains of both STF1 and HY5 have similar binding properties for recognizing ACGT-containing elements (ACEs). [Although] the G-box is a known target site for the HY5 protein, the C-box sequences are the preferred binding sites for both STF1 and HY5."[1]
"The combination of an [ACGT-containing element] ACE and a MRE confers light responsiveness to the CFI, F3H and FLS promoters."[2]
"Upstream from the transcriptional start site, several motifs were found [...]. A typical TATA box is located at -43. The CAAT consensus sequence cannot be found between -80 and -120; however, two sequence motifs (GCGCCC, GGGCAG), which are homologous to the consensus sequences for the Spl-binding site, GGGCGG (GC box) [19] were found around -114 and -570. The GC box has been found in promoters of many viral and cellular genes [20], and acts as a binding site of a protein, Spl, which is necessary for transcriptional activity. A pyrimidine box (CCTTT) and Box I (GCAGTG) which are part of the GA response complex [21] were found at -208 and -256. Two 8 bp sequences (CACGTCGC, CACGTAAC) which are similar to an ABA response element (ABRE, CACGTGGC) [22] were located at -308, -648 relative to the + 1 site. The core sequence of the ABA response element (ACGT) is the binding site for basic leucine zipper transcriptional factors or common plant regulatory factors (CPRFs) [23]."[3]
