摘要：
U6 snRNA sequences required for assembly of U4/U6 snRNP and splicing complexes were determined by in vitro reconstitution of snRNPs. Both mutagenesis and chemical modification/interference assays identify a U6 snRNA domain required for U4/U6 snRNP formation. The results support the existence of a U4/U6 snRNA interaction domain previously proposed on the basis of phylogenetic evidence. In addition, two short U6 snRNA regions flanking the U4/U6 interaction domain are essential to assemble the U4/U6 snRNP into splicing complexes. These two regions may represent binding sites for splicing factors or may facilitate the formation of an alternative U6 snRNA secondary structure during spliceosome assembly.
