Function

PUS1_YEAST Formation of pseudouridine at positions 27 and 28 in the anticodon stem and loop of transfer RNAs; at positions 34 and 36 of intron-containing precursor tRNA(Ile) and at position 35 in the intron-containing tRNA(Tyr) (PubMed:9671058, PubMed:10356324, PubMed:25219674). Catalyzes pseudouridylation at position 44 in U2 snRNA (PubMed:25219674). Also catalyzes pseudouridylation of mRNAs (PubMed:25219674, PubMed:31477916).^{[1] [2] [3] [4]}
