Small Cajal body specific RNA 8 (also known as SCARNA8 or U92) is a small nucleolar RNA found in Cajal bodies and believed to be involved in the pseudouridylation ( isomerisation of uridine to pseudouridine) of U2 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]
U92 belong to the H/ACA box class of guide RNAs as it has the predicted hairpin-hinge-hairpin-tail structure, conserved H/ACA-box motifs and is found associated with GAR1. [1] It is predicted to guide the pseudouridylation of residues U44 in U2 snRNA. [1] This snoRNA is related to the mouse H/ACA box snoRNA MBI-57. [2]
