Aligns to 81:226 / 315 (46.3%), covers 52.3% of PF01170, 26.4 bits

function: Catalyzes the two 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. Hypermethylates the m3G cap on TLC1 telomerase which affects telomere silencing and telomere length regulation. Required for pre-mRNA splicing, pre-rRNA processing and small ribosomal subunit synthesis. Involved in nucleolar structural organization.
catalytic activity: a 5'-end (N(7)-methyl 5'-triphosphoguanosine)-ribonucleoside in mRNA + S-adenosyl-L-methionine = a 5'-end (N(2),N(7)-dimethyl 5'- triphosphoguanosine)-ribonucleoside in mRNA + H(+) + S-adenosyl-L- homocysteine (RHEA:67620)
catalytic activity: a 5'-end (N(2),N(7)-dimethyl 5'-triphosphoguanosine)- ribonucleoside in mRNA + S-adenosyl-L-methionine = a 5'-end (N(2),N(2),N(7)-trimethyl 5'-triphosphoguanosine)-(ribonucleoside) in mRNA + H(+) + S-adenosyl-L-homocysteine (RHEA:67624)
subunit: Monomer (By similarity). Interacts with the spliceosomal snRNP core component SMB1 and the snoRNP components CBF5 and NOP58.

Aligns to 667:761 / 853 (11.1%), covers 52.3% of PF01170, 26.1 bits

function: 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 (By similarity).
