CC -!- FUNCTION: Bifunctional mRNA-capping enzyme exhibiting RNA 5'-
CC triphosphate monophosphatase activity in the N-terminal part and mRNA
CC guanylyltransferase activity in the C-terminal part. Catalyzes the
CC first two steps of cap formation: by removing the gamma-phosphate from
CC the 5'-triphosphate end of nascent mRNA to yield a diphosphate end, and
CC by transferring the GMP moiety of GTP to the 5'-diphosphate terminus of
CC RNA via a covalent enzyme-GMP reaction intermediate.
CC {ECO:0000256|PIRNR:PIRNR036958}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 5'-end diphospho-ribonucleoside in mRNA + GTP + H(+) = a 5'-
CC end (5'-triphosphoguanosine)-(ribonucleoside) in mRNA + diphosphate;

CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000256|PIRNR:PIRNR036958}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the eukaryotic GTase
CC family. {ECO:0000256|PIRNR:PIRNR036958}.
CC -!- SIMILARITY: In the N-terminal section; belongs to the non-receptor
CC class of the protein-tyrosine phosphatase family.
