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)."[1]
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')."[1]
"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."[1]
An H box has a consensus sequence of 3'-ACACCA-5'.[2]
The combined consensus sequence is 5'-ACAGGA-3'.[1]
