- Name
- 7-methylguanosine cap hypermethylation
- Ontology or CV name
- GO biological process
- Definition
- Hypermethylation of the 7-(mono)methylguanosine (m(7)G) cap structure at the N2 position of the guanine base 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.
