Pseudouridylate synthase that catalyzes pseudouridylation of tRNAs and mRNAs . Acts on positions 27/28 in the anticodon stem and also positions 34 and 36 in the anticodon of an intron containing tRNA . Also catalyzes pseudouridylation of mRNAs: mediates pseudouridylation of mRNAs with the consensus sequence 5'-UGUAG-3' . Acts as a regulator of pre-mRNA splicing by mediating pseudouridylation of pre-mRNAs at locations associated with alternatively spliced regions . Pseudouridylation of pre-mRNAs near splice sites directly regulates mRNA splicing and mRNA 3'-end processing . Involved in regulation of nuclear receptor activity through pseudouridylation of SRA1 mRNA .
[Isoform 1]: Mitochondrion .; [Isoform 2]: Nucleus . Cytoplasm .
Widely expressed (PubMed:15108122). High levels of expression found in brain and skeletal muscle (PubMed:15108122).
