Term ID

GO:0031429

Synonyms

• box H/ACA small nucleolar ribonucleoprotein complex
• box H/ACA snoRNP pseudouridylase complex

Definition

A box H/ACA small nucleolar ribonucleoprotein complex located in the nucleolus that catalyzes pseudouridylation of ribosomal RNA residues. The complex is composed of four different core proteins that assemble onto a H/ACA guide RNA scaffold that identifies specific uridines in rRNA for modification during ribosome synthesis. (3)
