CC   -!- FUNCTION: Component of the cleavage and polyadenylation factor (CPF)
CC       complex, which plays a key role in polyadenylation-dependent pre-mRNA
CC       3'-end formation and cooperates with cleavage factors including the
CC       CFIA complex and NAB4/CFIB. {ECO:0000250|UniProtKB:Q01329}.
CC   -!- SUBUNIT: Component of the cleavage and polyadenylation factor (CPF)
CC       complex, which is composed of cft1, cft2, ysh1, pta1, swd2, pfs2, dis2,
CC       yth1, ssu72, and fip1. {ECO:0000269|PubMed:14617822}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:16823372}.
CC   -!- SIMILARITY: To yeast PTA1. {ECO:0000305}.
