Changes in MCM2–7 proteins at senescence

open access: yesGenes and Genetic Systems, 2019
Cellular aging is characterized by the loss of DNA replication capability and is mainly brought about by various changes in chromatin structure. Here, we examined changes in MCM2-7 proteins, which act as a replicative DNA helicase, during aging of human WI38 fibroblasts at the single-cell level.

Is the MCM2–7 complex the eukaryotic DNA replication fork helicase?

Current Opinion in Genetics and Development, 2001
The MCM2-7 complex is essential for both the initiation and elongation phases of eukaryotic chromosome replication. There is some evidence that MCM2-7 proteins may act as a DNA helicase; at the same time, a variety of other DNA helicases have also been implicated in the replication of eukaryotic chromosomes.
