ACA70 was originally cloned from HeLa cells and belongs to the H/ACA box class of snoRNAs as it has the predicted hairpin-hinge-hairpin-tail structure, has the conserved H/ACA-box motifs and is found associated with GAR1 protein.
ACA70 was initially isolated from HeLa cells and categorizes within the class of snoRNAs designated as H/ACA box, characterized by a distinctive hairpin-hinge-hairpin-tail structure, conserved motifs, and its association with the GAR1 protein.
