Specific accessory sequences in Saccharomyces cerevisiae introns control assembly of pre-mRNAs into spliceosomes.

A Newman 1
PMCID: PMC553856  PMID: 3322814

Abstract

In experiments involving deletion and rearrangement of intron sequences two small regions of the intron in the yeast CYH2 ribosomal protein gene were found to play important roles in splicing of the pre-mRNA. One element lies downstream of the 5' splice site, and the other is upstream of the branchpoint sequence UACUAAC. Deletion of the element upstream of the branchpoint prevents spliceosome formation and blocks splicing in vivo and in vitro. Deletion of the element downstream of the 5' splice site does not on its own block splicing but rescues spliceosome formation and splicing of pre-mRNA lacking the element upstream of the branchpoint. These elements correspond to two regions of sequence complementarity which are a conserved feature of the introns in yeast pre-mRNAs. Mixing and matching of the elements from the ACT1 and CYH2 gene introns showed that these elements can cooperate in an intron-specific fashion to control spliceosome assembly.
