Homo sapiens ACA56 snoRNA
This H/ACA box RNA was cloned by Kiss et al. (2004) from a HeLa cell extract immunoprecipitated with an anti-GAR1 antibody. It is predicted to guide the pseudouridylation of residue U1664 of 28S rRNA. The pseudouridylation of this residue was previously reported by Ofengand and Bakin (1997). ACA56 and ACA36 share the same host gene (dyskerin).
