box C/D methylation guide snoRNP complex

Term ID

GO:0031428

Synonyms

• box C/D small nucleolar ribonucleoprotein complex
• box C/D snoRNP complex
• box C/D snoRNP ribose 2'-O methylase complex
• box C/D snoRNP ribose-2'-O-methyltransferase complex
• box C/D sRNP complex

Definition

A ribonucleoprotein complex containing a box C/D type RNA that is capable of ribose-2'-O-methylation of target RNAs. Box C/D type RNAs are widespread in eukaryotes and in Archaea, suggesting that an RNA-based guide mechanism for directing specific RNA 2'-O-ribose methylations was present in the common ancestor of Archaea and Eukarya.
