Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Component of the cleavage and polyadenylation factor (CPF) complex, which plays a key role in polyadenylation-dependent pre-mRNA 3'-end formation and cooperates with cleavage factors including the CFIA complex and NAB4/CFIB. Component of the APT complex, which may be involved in polyadenylation-independent transcript 3'-end formation. PTI1 is required for 3'-end formation of snoRNAs.
