===Methyltransferase domain of human Trimethylguanosine Synthase 1 (TGS1) bound to m7GTP and adenosyl-homocysteine (active form)===
== Function ==
 
[https://www.uniprot.org/uniprot/TGS1_HUMAN TGS1_HUMAN] Catalyzes the 2 serial methylation steps for the conversion of the 7-monomethylguanosine (m(7)G) 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.<ref>PMID:11517327</ref> <ref>PMID:11912212</ref> <ref>PMID:16687569</ref> <ref>PMID:18775984</ref>
