P1-7-Methylguanosine-P3-adenosine-5',5'-triphosphate
N(7)-methyl-GpppA is a guanosine 5'-phosphate that is 7-methyl-GTP(1+) in which the hydroxy group of the terminal phosphate is substituted by an adenosyl group. It is a cap analog that can be incorporated into mRNA. It is a guanosine 5'-phosphate, a purine ribonucleoside 5'-triphosphate and an adenosine 5'-phosphate. It is functionally related to a 7-methyl-GTP(1+). It is a conjugate acid of a (N(7)-methyl 5'-triphospho-guanosine)-adenosine(2-).
