In molecular biology, Small Cajal body specific RNA 13 (also known as scaRNA13 or U93) is a small nucleolar RNA found in Cajal bodies and believed to be involved in the pseudouridylation of U2 and U5 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]
U93 is composed of two tandemly arranged box H/ACA box sequence motifs and belongs to the H/ACA box class of guide RNAs.[2] U93 is predicted to guide pseudouridylation of U2 spliceosomal snRNA residue U54 and residue U53 of snRNA U5.[2][3][4]
