Notes Small nuclear RNA (snRNA) is known to be involved in pre-mRNA splicing as an RNA component of snRNP. 2,2,7-trimethylated guanosine (m<sub>3</sub>G/TMG) is a modified nucleoside at the 5&rsquo;-cap site of U snRNAs except for U6 snRNA. Shortly after transcription, 7-methylguanosine (m<sup>7</sup>G), called cap structure, is added to 5&rsquo;-end of newly synthesized U snRNA and m<sup>7</sup>G-capped U snRNA is exported to the cytoplasm. The m<sup>7</sup>G-cap is converted to m<sub>3</sub>G-cap, which is a hypermethylated structure of 5&rsquo;-end, by cytoplasmic catalytic protein TSG1 and the m<sub>3</sub>G-capped U snRNA forms snRNP with Sm proteins in the cytoplasm, followed by entry into the nucleus. The m<sub>3</sub>G-capped snRNP plays a role in regulation of pre-mRNA splicing as a part of spliceosome in nucleus. It is also reported that U3 and U8 snoRNA, localized to Cajal body during RNP biogenesis, possess m<sub>3</sub>G-cap structure.
