H/ACA ribonucleoprotein complex subunit GAR1; Non-catalytic component of the H/ACA small nucleolar ribonucleoprotein (H/ACA snoRNP), which catalyzes pseudouridylation of rRNA and is required for ribosome biogenesis. 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. The H/ACA snoRNP complex also mediates pseudouridylation of other types of RNAs. The H/ACA snoRNP complex mediates pseudouridylation at position 93 in U2 snRNA.

NOP5-LIKE NUCLEOLAR PROTEIN.

NUCLEOLAR PROTEIN SIMILAR TO NOP5.

rRNA 2'-O-methyltransferase fibrillarin; S-adenosyl-L-methionine-dependent methyltransferase that has the ability to methylate both RNAs and proteins. Involved in pre-rRNA processing. Utilizes the methyl donor S-adenosyl-L-methionine to catalyze the site-specific 2'-hydroxyl methylation of ribose moieties in pre-ribosomal RNA. Site specificity is provided by a guide RNA that base pairs with the substrate. Methylation occurs at a characteristic distance from the sequence involved in base pairing with the guide RNA. Also acts as a protein methyltransferase by mediating methylation of 'Gl [...]

Telomerase reverse transcriptase; Telomerase is a ribonucleoprotein enzyme essential for the replication of chromosome termini in most eukaryotes. It elongates telomeres. It is a reverse transcriptase that adds simple sequence repeats to chromosome ends by copying a template sequence within the RNA component of the enzyme.

Ribonucloprotein; Common component of the spliceosome and rRNA processing machinery; Belongs to the eukaryotic ribosomal protein eL8 family.

60S ribosome subunit biogenesis protein NIP7; Required for proper 27S pre-rRNA processing and 60S ribosome subunit assembly; Belongs to the NIP7 family.
