molecular function |
| GO:0003723 | | RNA binding | | Interacting selectively and non-covalently with an RNA molecule or a portion thereof. |
| GO:0004482 | | mRNA (guanine-N7-)-methyltransferase activity | | Catalysis of the reaction: S-adenosyl-L-methionine + G(5')pppR-RNA = S-adenosyl-L-homocysteine + m7G(5')pppR-RNA. m7G(5')pppR-RNA is mRNA containing an N7-methylguanine cap; R may be guanosine or adenosine. |
| GO:0008168 | | methyltransferase activity | | Catalysis of the transfer of a methyl group to an acceptor molecule. |
| GO:0016740 | | transferase activity | | Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2. |
biological process |
| GO:0006370 | | 7-methylguanosine mRNA capping | | Addition of the 7-methylguanosine cap to the 5' end of a nascent messenger RNA transcript. |
| GO:0036265 | | RNA (guanine-N7)-methylation | | The addition of a methyl group to the N7 atom in the base portion of a guanine nucleotide residue in an RNA molecule. |
| GO:0006397 | | mRNA processing | | Any process involved in the conversion of a primary mRNA transcript into one or more mature mRNA(s) prior to translation into polypeptide. |
| GO:0032259 | | methylation | | The process in which a methyl group is covalently attached to a molecule. |
cellular component |
| GO:0005634 | | nucleus | | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. |
