7-Methylguanosine (m7G) is a purine nucleoside that has been modified. It is a methylated form of guanosine that, when found in human urine, may be a biomarker for certain cancers. 7-methylguanosine has been used in RNAs to study and examine the reaction evolving methylguanosine. It also acts as a blocking group at the 5′ end of mRNA.

The 7-Methylguanosine structure is also known as a cap. It is found at the 5′ end of cytoplasmic mRNA.

RNA capping is a critical step in the production of a stable mature mRNA capable of translation, and it is involved in many functional processes.

The Cap-Binding-Complex (CBC) binds exclusively to m7G-capped mRNA and is responsible for exporting it from the nucleus to the cytoplasm. Other translation factors are used in its place to be recognized by ribosomes. Thus, protein biosynthesis cannot begin without RNA capping. Furthermore, RNA capping serves as an identification group for recruiting protein factors for a variety of other critical cellular processes, such as pre-mRNA splicingpolyadenylation, and intracellular transport.

7-Methylguanosine has been used to remove residual phosphates from prerigor solution, the phosphate mop system, and the phosphorous standard solution.
