7-Methylguanosine is a modified nucleoside consisting of a guanine base linked to a ribose sugar with a methyl group attached to the 7th position of the guanine. It is commonly found in the 5' cap structure of eukaryotic mRNA molecules. The main function of 7-methylguanosine is to protect the mRNA from degradation and assist in its translation. It plays a crucial role in facilitating the binding of the ribosome to the mRNA during protein synthesis. The location of 7-methylguanosine is primarily at the 5' end of mRNA molecules, where it serves as a recognition signal for various cellular processes involved in mRNA processing, export, and translation.
