Homo sapiens ACA46 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 U649 of 18S rRNA. The pseudouridylation of this residue was experimentally confirmed by primer extension mapping by Kiss et al. (2004). ACA46 and ACA50 share the same host gene (KIAA1007).
