Catalyzes the 2 serial methylation steps for the conversion of the 7-monomethylguanosine (m7G) caps of snRNAs and snoRNAs to a 2,2,7-trimethylguanosine (m(2,2,7)G) cap structure.
The enzyme is specific for guanine, and N7 methylation must precede N2 methylation.
Hypermethylation of the m7G cap of U snRNAs leads to their concentration in nuclear foci, their colocalization with coilin and the formation of canonical Cajal bodies (CBs).
Plays a role in transcriptional regulation.
Applications:Suitable for use in ELISA and Immunohistochemistry.
Other applications not tested.
Recommended Dilution:Immunohistochemistry: 1:20-1:200Optimal dilutions to be determined by the researcher.
