Eco1是在DNA复制过程中建立姐妹染色单体内聚的乙酰转移酶。一种带有eco1突变的芽殖酵母菌株与罗伯茨综合征相似,其核糖体DNA (rDNA)转录减少,并具有饥饿的转录特征。我们发现,删除fob1(一种编码rDNA区域特异性复制叉阻断蛋白的基因)可以挽救rRNA的产生,并部分挽救全基因组的转录。进一步的研究表明,FOB1的缺失纠正了eco1突变体中出现的全基因组复制缺陷、核仁结构和rDNA分离。我们的研究强调,在rDNA位点内聚蛋白的存在在控制全局DNA复制和基因表达中起着核心作用。
Eco1 is the acetyltransferase that establishes sister-chromatid cohesion during DNA replication. A budding yeast strain with an eco1 mutation that genocopies Roberts syndrome has reduced ribosomal DNA (rDNA) transcription and a transcriptional signature of starvation. We show that deleting FOB1—a gene that encodes a replication fork-blocking protein specific for the rDNA region—rescues rRNA production and partially rescues transcription genome-wide. Further studies show that deletion of FOB1 corrects the genome-wide replication defects, nucleolar structure, and rDNA segregation that occur in the eco1 mutant. Our study highlights that the presence of cohesin at the rDNA locus has a central role in controlling global DNA replication and gene expression.
