Same partners,different dance: Involvement of DNA replication proteins in centrosome regulation |
| |
Abstract: | Genome replication is the most fundamental element of the continuity of life. In eukaryotes, DNA replication is regulated by an elegant network of many different protein factors to ensure the timely and accurate copying of their entire genome once per cell cycle. The replication factors include the maintenance (MCM) proteins, Cdt1, Cdc6, Cdc7, Cdc45, and geminin. All of these proteins are involved in the regulation of DNA replication at the initiation step. Interestingly, recent studies have shown that some of these replication proteins also localize to the centrosome, often throughout the entire cell cycle. These centrosomally localized replication proteins appear to play essential roles in the regulation of centrosome biogenesis, suggesting that genome replication and segregation are regulated interdependently. In this review, we summarize and discuss the inter-dependent regulation played by some of the replication proteins. |
