CC -!- FUNCTION: Second step of mRNA capping. Transfer of the GMP moiety of
CC GTP to the 5'-end of RNA via an enzyme-GMP covalent reaction
CC intermediate. {ECO:0000256|PIRNR:PIRNR036959}.
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 Xref=Rhea:RHEA:67012, Rhea:RHEA-COMP:17165, Rhea:RHEA-COMP:17166,

CC Evidence={ECO:0000256|ARBA:ARBA00024520};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:67013;
CC Evidence={ECO:0000256|ARBA:ARBA00024520};
CC -!- SUBUNIT: Heterodimer. {ECO:0000256|PIRNR:PIRNR036959}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000256|PIRNR:PIRNR036959}.
CC -!- SIMILARITY: Belongs to the eukaryotic GTase family.
