[[http://www.uniprot.org/uniprot/NEP1_YEAST 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.<ref>PMID:11694595</ref> <ref>PMID:11935223</ref> <ref>PMID:15590835</ref> <ref>PMID:20972225</ref> <ref>PMID:21087996</ref>
