SNU17 2
Protein Product
U2 snRNP complex subunit IST3
Feature Type
ORF , Verified
Component of the U2 snRNP; required for the first catalytic step of splicing and for spliceosomal assembly; interacts with Rds3p and is required for Mer1p-activated splicing; diploid mutants have a specific defect in MATa1 pre-mRNA splicing which leads to haploid gene expression in diploids 2 3 4 5
