Gene:
RNA guanylyltransferase and 5'-phosphatase
Gene ID:
194591
Symbol:
RNGTT
Species:
1000
Description:
Bifunctional mRNA capping enzyme exhibiting RNA 5'- triphosphatase activity in the N-terminal part and mRNA guanylyltransferase activity in the C-terminal part. Catalyzes the first two steps of cap formation: by removing the gamma-phosphate from the 5'-triphosphate end of nascent mRNA to yield a diphosphate end, and by transferring the gmp moiety of GTP to the 5'-diphosphate terminus.
