Protein attributes
| Sequence length | 476 AA. |
| Sequence status | Complete. |
| Protein existence | Inferred from homology. |
General annotation (Comments)
| Function | First step of mRNA capping. Converts the 5'-triphosphate end of a nascent mRNA chain into a diphosphate end By similarity. |
| Catalytic activity | A 5'-phosphopolynucleotide + H2O = a polynucleotide + phosphate. |
| Cofactor | Divalent ions By similarity. |
| Subunit structure | The mRNA-capping enzyme is composed of two separate chains alpha and beta, respectively a mRNA guanylyltransferase and an RNA 5'-triphosphatase By similarity. |
| Subcellular location | Nucleus By similarity. |
| Sequence similarities | Belongs to the fungal TPase family. |
