Pseudouridine (abbreviated Ψ) is the C-glycoside isomer of the nucleoside uridine, and it is the most prevalent of the over one hundred different modified nucleosides found in RNA.[1] Ψ is found in all species and in all classes of RNA except mRNA.[2] Ψ is formed by enzymes called Ψ synthases, which post-transcriptionally isomerize specific uridine residues in RNA in a process termed pseudouridylation.[3]
