box C/D methylation guide snoRNP complex
box c/d methylation guide snornp complex
"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."
