Abstract

In the spliceosome, the pre-mRNA, U2 and U6 snRNAs fold into a catalytic structure exhibiting striking similarities with domain V and VI of group II introns. Building of this tripartite structure implies that an evolutionary conserved base pairing between U4 and U6 snRNAs should be disrupted to allow potentially U6 catalytic residue to interact with U2 snRNAs and the pre-mRNA. The steps leading to U4/U6 disruption have been recently discovered and have been shown to involve a modification of the 3' end of U6 snRNA and the hnRNP C protein.
