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.

Nop10p is a nucleolar protein that is specifically associated with H/ACA snoRNAs. It is essential for normal 18S rRNA production and rRNA pseudouridylation by the ribonucleoprotein particles containing H/ACA snoRNAs (H/ACA snoRNPs). Nop10p is probably necessary for the stability of these RNPs. Length = 52

>PF04135 Nop10p: Nucleolar RNA-binding protein, Nop10p family; InterPro: IPR007264 H/ACA ribonucleoprotein particles (RNPs) are a family of RNA pseudouridine synthases that specify modification sites through guide RNAs
More than 100 mammalian H/ACA RNAs form an equal number of ribonucleoproteins (RNPs) by associating with the same four core proteins: Cbf5, Gar1, Nhp2 and Nop10. The function of these H/ACA RNPs is essential for biogenesis of the ribosome, splicing of precursor mRNAs (pre-mRNAs), maintenance of telomeres and probably for additional cellular processes []. Recent crystal structures of archaeal H/ACA protein complexes show how the same four proteins accommodate >100 distinct but related H/ACA RNAs []. The complex contains a stable core composed of Cbf5 and Nop10, to which Gar1 and Nhp2 subsequently bind, the complex interacts with snoRNAs []. In eukaryotes Nop10 is a nucleolar protein that is specifically associated with H/ACA snoRNAs. It is essential for normal 18S rRNA production and rRNA pseudouridylation by the ribonucleoprotein particles containing H/ACA snoRNAs (H/ACA snoRNPs). Nop10 is probably necessary for the stability of these RNPs [].; PDB: 2RFK_B 3LWR_B 2HVY_C 3HAX_C 3MQK_B 3LWO_B 3LWV_B 3HAY_C 3HJY_B 2EY4_E ....

This model represents the large subunit, DP2, of a two subunit novel Archaeal replicative DNA polymerase first characterized for Pyrococcus furiosus. Structure of DP2 appears to be organized as a ~950 residue component separated from a ~300 residue component by a ~150 residue intein. The other subunit, DP1, has sequence similarity to the eukaryotic DNA polymerase delta small subunit.
