Function

[RS7A_YEAST] Involved in nucleolar processing of pre-18S ribosomal RNA and ribosome assembly.^[1] [UTP21_YEAST] Involved in nucleolar processing of pre-18S ribosomal RNA and ribosome assembly.^[2] [RCL1_YEAST] Does not have cyclase activity. Plays a role in 40S-ribosomal-subunit biogenesis in the early pre-rRNA processing steps at sites A0, A1 and A2 that are required for proper maturation of the 18S RNA. Essential for viability. [NEP1_YEAST] S-adenosyl-L-methionine-dependent pseudouridine N(1)-methyltransferase that methylates pseudouridine at position 1189 (Psi1189) in 18S rRNA. Involved the biosynthesis of the hypermodified N1-methyl-N3-(3-amino-3-carboxypropyl) pseudouridine (m1acp3-Psi) conserved in eukaryotic 18S rRNA. N1-methylation is independent on acp-modification at the N3-position of U1191. Has also an essential role in 40S ribosomal subunit biogenesis independent on its methyltransferase activity, facilitating the incorporation of ribosomal protein S19 (RPS19A/RPS19B) during the formation of pre-ribosomes.^[3] ^[4] ^[5] ^[6] ^[7] [RRP9_YEAST] Involved in nucleolar processing of pre-18S ribosomal RNA. Required for efficient pre-rRNA cleavage at sites A0, A1 and A2, and biosynthesis of 18S rRNA.^[8] [RS9A_YEAST] Involved in nucleolar processing of pre-18S ribosomal RNA and ribosome assembly.^[9] [SNU13_YEAST] Common component of the spliceosome and rRNA processing machinery. In association with the spliceosomal U4/U6.U5 tri-snRNP particle, required for splicing of pre-mRNA. In association with box C/D snoRNPs, required for processing of pre-ribosomal RNA (rRNA) and site-specific 2'-O-methylation of substrate RNAs. Essential for the accumulation and stability of U4 snRNA, U6 snRNA, and box C/D snoRNAs.^[10] ^[11] ^[12] [RS6A_YEAST] Involved in nucleolar processing of pre-18S ribosomal RNA and ribosome assembly.^[13]
