A key question in the eukaryotic mismatch repair field is how strand excision is coordinated with mismatch recognition. In a recent issue of Molecular Cell, Dzantiev et al. present evidence that the replication factors PCNA and RFC modulate the directionality of EXOI-mediated excision.
真核生物错配修复领域的一个关键问题是，链切除如何与错配识别相协调。在最近一期的《分子细胞》杂志上，赞季耶夫等人提供了证据，证明复制因子增殖细胞核抗原（PCNA）和复制因子C（RFC）可调节EXOI介导的切除的方向性。
