ACA58 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.
ACA58 originated from HeLa cells and belongs to the group of small nucleolar RNAs (snoRNAs) known as H/ACA box snoRNAs due to its predicted structural arrangement and conservation of specific motifs. It is also associated with the GAR1 protein.
