Homo sapiens ACA5 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 residues U1625 and U1238 of 18S rRNA. The pseudouridylation of U1625 residue was previously reported by Maden and Wakeman (1988), but these authors could not determine whether U1238 or U1239 was modified. ACA5, ACA5b and ACA5c share the same host gene (TBRG4).
