Summary: Enables mRNA binding activity. Contributes to pseudouridine synthase activity. Involved in box H/ACA sno(s)RNA 3'-end processing and pseudouridine synthesis. Part of box H/ACA snoRNP complex. Human ortholog(s) of this gene implicated in X-linked dyskeratosis congenita; aplastic anemia; and dyskeratosis congenita. Orthologous to human DKC1 (dyskerin pseudouridine synthase 1). [provided by Alliance of Genome Resources, Jan 2025]

What's a GeneRIF?

rRNA pseudouridylation defects resulted from a deficient pseudouridylate synthetase affect ribosomal ligand binding and translational fidelity from yeast to human cells.
Title: rRNA pseudouridylation defects affect ribosomal ligand binding and translational fidelity from yeast to human cells.
The authors demonstrate that Shq1p binds the pseudourydilating enzyme Cbf5p through the C-terminal domain, in synergy with the N-terminal domain.
Title: The box H/ACA snoRNP assembly factor Shq1p is a chaperone protein homologous to Hsp90 cochaperones that binds to the Cbf5p enzyme.
box H/ACA RNP assembly factor Naf1p contains a domain homologous to Gar1p mediating its interaction with Cbf5p
Title: The box H/ACA RNP assembly factor Naf1p contains a domain homologous to Gar1p mediating its interaction with Cbf5p.
two molecules of Cbf5p interact with a binding platform constituted by the 5' end of the RNA, the single-stranded hinge domain containing the conserved H box, and the 3' end of the molecule, including the conserved ACA box
Title: Analysis of the binding of the N-terminal conserved domain of yeast Cbf5p to a box H/ACA snoRNA.

Preferred Names: pseudouridine synthase CBF5

NP_013276.1

Pseudouridine synthase catalytic subunit of box H/ACA snoRNPs; acts on large and small rRNAs, on snRNA U2, and on some mRNAs; mutations in human ortholog dyskerin cause the disorder dyskeratosis congenita; small nucleolar ribonucleoprotein particles are also known as snoRNPs
