small nucleolar RNA, H/ACA box 14B

Small nucleolar RNAs (snoRNAs) are 60-150 nt long non-coding RNAs, and include two groups: C/D box snoRNAs and H/ACA box snoRNAs. The C/D box snoRNAs are guides for the 2'-O-ribose methylation of rRNAs or snRNAs. The H/ACA box snoRNAs are guides for the isomerization of uridine residues into pseudouridine. This gene belongs to the group of the H/ACA box snoRNAs, and functions in 18S rRNA pseudouridylation at position U966. The gene duplication generates a 91% identical copy on chromosome 7.
