| Term | 7-methylguanosine cap hypermethylation | ID (Ontology) | GO:0036261 (Gene Ontology) | |||||||
| Definition | Hypermethylation of the 7-(mono)methylguanosine (m(7)G) cap structure at the 2' position of the guanosine residue to convert a mono-methylated cap to a 2,2,7-trimethylguanosine cap structure. This type of cap modification occurs on small nuclear RNAs (snRNAs) and small nucleolar RNAs (snoRNAs) and is dependent on prior guanine-N7 methylation.[ PubMed:11983179 PubMed:18775984 ] | |||||||||
| Also Known As | "2,2,7-trimethylguanosine cap formation" ; "conversion of m(7)G to m(3)G" ; "m(7)G cap hypermethylation" (for all, see Synonyms field below) | |||||||||
