In molecular biology, small Cajal body specific RNA 4 (also known as ACA26) is believed to be a guide RNA of the H/ACA box class, since it has the predicted hairpin-hinge-hairpin-tail structure, conserved H/ACA-box motifs, and is found associated with GAR1.
In molecular biology, ACA26, also referred to as small Cajal body specific RNA 4, is considered a guide RNA of the H/ACA box class due to its structural characteristics, including a hairpin-hinge-hairpin-tail configuration and conserved motifs, which are indicative of its role in association with GAR1.
