The "H-box [is] from the bean chalcone synthase gene Chs15 [23,24]."[1]

The "Phaseolus vulgaris chalcone synthase (PvCHS15)" gene has three H boxes between the G box and the TATA box, where each binds to MYB, KAP 2, and KAP 1 downstream from the G box, respectively.[1]

"Functional studies with the H-box indicated that it cannot function to a high level alone. Gain of function experiments, however, show that it is active in combination with a G-Box element [...] in transgenic tobacco plants in establishing the characteristic tissue-specific pattern of expression and mutations in either the H-box or G-Box reduced the response to tobacco mosaic virus (TMV) infection [24,30]."[1]

"A bZIP protein from soybean binds to the G-Box in the bean Chs15 promoter [36•]. This protein, G/HBF-1, can also bind to the adjacent H-box."[1]

"Although the mRNA and protein levels of G/HBF-1 do not increase during the induction of its putative target genes, the protein itself is rapidly phosphorylated and in vitro phosphorylation enhances binding to one (H-box III) out of the three H-boxes present in the Chs15 promoter."[1]

H box in animals

"A testis/brain RNA-binding protein, TB-RBP, binds to the Y- and H-boxes in the Prm2 3′ UTR and represses translation of a reporter mRNA in rabbit reticulocyte lysates [9]. The Y- and H-boxes are found in many transcripts expressed in the testis and brain, including Prm1, Prm2, Tnp1, and Tau [10]."[2]

H-boxes

"Two distinct sequence elements, the H-box (consensus CCTACC(N)7CT) and the G-box (CACGTG), are required for stimulation of the chs15 promoter by 4-CA."[3]

H box consensus sequences

"The box H/ACA snoRNAs were most recently recognized as a small RNA family by virtue of an ACA trinucleotide located 3 nt upstream of the mature snoRNA 3' end (41). In addition to this ACA box, they have the consensus H box sequence (5'-ANANNA-3') but have no other primary sequence identity. Despite this lack of primary sequence conservation, the H and ACA boxes are embedded in an evolutionarily conserved hairpin-hinge-hairpin-tail core secondary structure with the H box in the single-stranded hinge region and the ACA box in the single-stranded tail (5, 16)."[4]

The "3' end of mature hTR (45) has an ACA trinucleotide 3 nt upstream of its 3' end. In addition, the 3' region of hTR contains a single H box consensus sequence (5'-AGAGGA-3')."[4]

"Comparison with the murine telomerase RNA (mTR) (7) suggests that the snoRNA-like features of hTR are evolutionarily conserved. The mTR 3' end (nt 169 to 397 as numbered in reference 25) has ~76% sequence identity with the corresponding region of hTR (nt 211 to 451) and includes consensus H (5'-ACAGGA-3') and ACA box sequences."[4]

An H box has a consensus sequence of 3'-ACACCA-5'.[5]

H-box consensus sequences

The earlier H-box consensus sequence is CCTACC(N)7CT.[3]

H box in Solanaceae has the following consensus sequence 3'-CC(A/T)ACCNNNNNNN(A/C)T-5'.[6]
