A U1 snRNA:pre-mRNA base pairing interaction is required early in yeast spliceosome assembly but does not uniquely define the 5' cleavage site.
We analyzed the effects of suppressor mutations in the U1 snRNA (SNR19) gene from Saccharomyces cerevisiae on the splicing of mutant pre-mRNA substrates. The results indicate that pairing between U1 snRNA and the highly conserved position 5 (GTATGT) of the intron occurs early in spliceosome assembly...
