Homo sapiens ACA5b snoRNA
This H/ACA box RNA was cloned by Kiss et al. (2004) from a HeLa cell extract immunoprecipitated with an anti-GAR1 antibody. As its close paralogues ACA5 and ACA5c, this RNA is predicted to guide the pseudouridylation of residue U1238, and possibly U1625, of 18S rRNA. ACA5, ACA5b and ACA5c share the same host gene (TBRG4).
