Vaccinia Capping Enzyme, GMP grade (GMP-VCS-VE101)

  • Description: Vaccinia Capping Enzyme adds the 7-methylguanosine cap structure (Cap0) structure to the 5' end of mRNA. Cap0 is a characteristic feature of RNA transcribed by RNA-polymerase II (i.e. mRNA) and is essential for efficient translation of mRNA in eukaryotic cells.
  • Applications: In vitro transcription, RNA modification, Labeling 5’ end of mRNA
  • Quality: GMP-Grade, Antibiotic-free and animal-free production, Suitable for manufacturing of mRNA therapeutics, Regulatory support documents available
  • Related Products: mRNA Cap 2'-O-Methyltransferase, GMP-MEH-VE101

Product Description The 7-methylguanosine cap structure(m7Gppp, Cap0) is a specific feature in eukaryotic mRNA, which is required for mRNA stability, splicing, nuclear export, effective translation, and mRNA decay. Vaccinia Capping Enzyme, a heterodimer of D1(844 aa) and D12(287 aa) subunits, adding the Cap0 structure to the 5' end of the RNA. The D1 subunit comprises an N-terminal RNA triphosphatase(TPase), a guanylyltransferase(GTase), and a C-terminal guanine-N7-methyltransferase(MTase). The D12 subunit binds and stimulates the MTase.
mRNA Cap 2'-O-Methyltransferase (Kactus #GMP-MEH-VE101) is required to generate Cap 1 structure that reduces cellular innate immune response when the RNA is used in vivo.
