< | [[http://www.uniprot.org/uniprot/SHQ1_YEAST SHQ1_YEAST]] Involved in the early biogenesis steps of box H/ACA snoRNP assembly.<ref>PMID:12228251</ref> [[http://www.uniprot.org/uniprot/CBF5_YEAST CBF5_YEAST]] Plays a central role in ribosomal RNA processing. Probable catalytic subunit of H/ACA small nucleolar ribonucleoprotein (H/ACA snoRNP) complex, which catalyzes pseudouridylation of rRNA. This involves the isomerization of uridine such that the ribose is subsequently attached to C5, instead of the normal N1. Pseudouridine ('psi') residues may serve to stabilize the conformation of rRNAs. May function as a pseudouridine synthase. Binds in vitro to centromeres and microtubules. It is a centromeric DNA-CBF3-binding factor which is involved in mitotic chromosome segregation. Essential for cell growth.<ref>PMID:8336724</ref> <ref>PMID:9315678</ref> <ref>PMID:9472021</ref> <ref>PMID:9848653</ref> <ref>PMID:10523634</ref> [[http://www.uniprot.org/uniprot/GAR1_YEAST GAR1_YEAST]] Required for ribosome biogenesis.
