Abstract excerpt
Recognition of 5' splice sites in pre-mRNA splicing is achieved in part by base pairing with U1 snRNA. We have used interactive suppression in the yeast Saccharomyces cerevisiae to look for other factors involved in 5' splice-site recognition. This approach identified an extragenic suppressor that activates a cryptic 5' splice site. The suppressor is a gene for U5 snRNA (snR7) with a single base mutation in a...
