Expression data from Saccharomyces cerevisiae strains carrying the rna14-1 or the rna15-1 allele

In the yeast Saccharomyces cerevisiae, cleavage factor I (CFI) and cleavage and polyadenylation factor (CPF) build the core of the transcription termination machinery在酿酒酵母（Saccharomyces cerevisiae）中，剪切因子I（cleavage factor I，CFI）与剪切与多聚腺苷酸化因子（cleavage and polyadenylation factor，CPF）共同构成转录终止分子机器的核心。
