Required for ribosome biogenesis and telomere maintenance. Part of the 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. Each rRNA can contain up to 100 pseudouridine ('psi') residues, which may serve to stabilize the conformation of rRNAs. May also be required for correct processing or intranuclear trafficking of TERC, the RNA component of the telomerase reverse transcriptase (TERT) holoenzyme.

In this work, we have uncovered a putative role of epigenetic regulation in a subset of human snoRNP complexes that are involved in the site-specific modification of RNA. We find that a subset of box C/D snoRNAs are methylated at the 1n position and that this blocks both 15.5k binding and the formation of the kinked conformation in vivo. PMID: 28623187
