Small Cajal body specific RNA 16 (also known as SCARNA16 or ACA47) is a small nucleolar RNA found in Cajal bodies and believed to be involved in the pseudouridylation (isomerisation of uridine to pseudouridine) of U1 spliceosomal RNA.
scaRNAs are a specific class of small nucleolar RNAs that localise to the Cajal bodies and guide the modification of RNA polymerase II transcribed spliceosomal RNAs U1, U2, U4, U5 and U12.[1]
ACA47 belongs to the H/ACA box class of guide RNAs as it has the predicted hairpin-hinge-hairpin-tail structure, the conserved H/ACA-box motifs and is found associated with GAR1.[2] ACA47 is predicted to guide the pseudouridylation of residue U5 of the U1 spliceosomal snRNA.[3]
