MMARY THUMPD2 installs N2-methylguanosine (m2G) at position 72 of the U6 snRNA, and this modification, which lies at the catalytic core of the spliceosome, is required for efficient splicing of weak splice sites. However, when during the U6 lifecycle this modification is installed and what features ...
How the relatively evolutionarily conserved spliceosome is able to manage the enormously expanded number of splicing events that occur in humans (~200,000 vs. ~400 reported for yeast) is not well understood. Here, we show deposition of one RNA modification-N2-methylguanosine (m2G)-on the G72 nucleos...
The internal stem loop (ISL) of the human U6 snRNA, which catalyzes pre-mRNA splicing, contains LARP7-dependent, snoRNA-guided 2′-O-methylations and an N2-methylguanosine (m2G) that is required for splicing of weak splice sites. Here, we show that installation of m2G72 by the THUMPD2-TRMT112 methylt...
