m3G cap hypermethylation of U1 small nuclear ribonucleoprotein (snRNP) in vitro: evidence that the U1 small nuclear RNA-(guanosine-N2)-methyltransferase is a non-snRNP cytoplasmic protein that requires a binding site on the Sm core domain.
The RNA components of small nuclear ribonucleoproteins (U snRNPs) possess a characteristic 5'-terminal trimethylguanosine cap structure (m3G cap). This cap is an important component of the nuclear localization signal of U snRNPs. It arises by hypermethylation of a cotranscriptionally added m7G cap....
