In molecular biology, Small Cajal body specific RNA 14 (also known as scaRNA14 or U100) is a small nucleolar RNA found in Cajal bodies.

scaRNAs are a specific class of small nucleolar RNAs which localise to the Cajal bodies and guide the modification of RNA polymerase II transcribed spliceosomal RNAs U1, U2, U4, U5 and U12.[1][2] U100 belongs to the H/ACA box class of guide RNAs as it has the predicted hairpin-hinge-hairpin-tail structure and the conserved H/ACA-box motifs.[3]

U100 is the human orthologue of mouse H/ACA snoRNA MBII-201 which is also included in this family.[4] U100 is predicted to guide the pseudouridylation of U2 snRNA at residue U7.[5]
