Conversion of specific uridine residues to pseudouridine and the addition of methyl groups to the 2′-hydroxyl groups

of specific riboses, that are important for the proper assembly and function of snRNPs in pre-mRNA splicing. 

These modifications occur in Cajal bodies, where they are directed by a class of snoRNA-like guide RNA molecules called scaRNAs (small Cajal body–associated RNAs)
