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.[1] In particular, ACA26 is predicted to guide the pseudouridylation of residues U39 and U41 in U2 snRNA.[1] Such scaRNAs are a specific class of small nuclear RNAs that localise to the Cajal bodies and guide the modification of RNA polymerase II transcribed spliceosomal RNAs U1, U2, U4, U5 and U12.[2]
