General description

The 2,2,7-trimethylguanosine cap structure is found on the 5’ end of small nuclear RNAs and small nucleolar RNAs. Initially, these RNA molecules are capped with 7-monomethylguanosine (m7G) which is then methylated by the trimethylguanosine synthase enzyme to form 2,2,7-trimethylguanosine. The synthesis of 2,2,7-trimethylguanosine occurs in the cytoplasm and is an important marker for nuclear localization of RNA molecules. Capping of RNAs is an important requirement for RNA transport and splicing processes. Uncapped RNAs are rapidly degraded by the 5′ exoribonuclease enzyme. 2,2,7-trimethylguanosine capping may play a role in the expression of viral RNAs.

Application

Anti-2, 2, 7-Trimethylguanosine Antibody, clone K121 is a high quality Mouse Monoclonal Antibody for the detection of 2, 2, 7-Trimethylguanosine & has been validated in ICC, PAI & IP.
