Abstract :
Homo sapiens ACA64 snoRNA. This H/ACA box RNA was characterized by bioinformatics, and its expression verified by Northern blot and primer extension in mouse (Schattner et al., 2006). It is predicted to guide the pseudo-uridylation of 28S rRNA U4331, as ACA 23. Two highly related copies are localized on human chr1 and chr4.
