Biogenesis of eukaryotic box C/D small nucleolar ribonucleoproteins initiates co-transcriptionally and requires the action of the assembly machinery including the Hsp90/R2TP complex, the Rsa1p:Hit1p ...
Box C/D ribonucleoprotein complexes are RNA-guided methyltransferases that methylate the ribose 2’-OH of RNA. The central ‘guide RNA’ has box C and D motifs at its ends, which are crucial for activity ...
