Homo sapiens ACA53 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 has no identified target RNA. Note that the sequence deposited in GenBank under accession AJ609478 (Homo sapiens ACA53 snoRNA gene) corresponds in fact to a portion of ACA24.
