PUS10 Proteins and Enzymes

Pseudouridination, the isomerization of uridine to pseudouridine, is the most common posttranscriptional nucleotidemodification found in RNA and is essential for biologic functions such as spliceosome biogenesis. Pseudouridylatesynthases, such as PUS10, catalyze pseudouridination of structural RNAs, including transfer, ribosomal, and splicingRNAs. These enzymes also act as RNA chaperones, facilitating the correct folding and assembly of tRNAs (McCleverty etal., 2007 (PubMed 17900615)).(supplied by OMIM)
