Term Name:	box H/ACA snoRNP complex
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.
