In molecular biology, Small Cajal body specific RNA 11 (also known as scaRNA11 or ACA57) is a small nucleolar RNA found in Cajal bodies.

scaRNAs are a specific class of small nuclear 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] ACA57 belongs 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] ACA57 is predicted to guide the pseudouridylation of the U5 spliceosomal RNA at position U43. [3]
