title: Regulation and Function of Cdt1; A Key Factor in Cell Proliferation and Genome Stability.
abstract: Successful cell proliferation requires efficient and precise genome duplication followed by accurate chromosome segregation. The Cdc10-dependent transcript 1 protein (Cdt1) is required for the first step in DNA replication, and in human cells Cdt1 is also required during mitosis. Tight cell cycle controls over Cdt1 abundance and activity are critical to normal development and genome stability. We review here recent advances in elucidating Cdt1 molecular functions in both origin licensing and kinetochore-microtubule attachment, and we describe the current understanding of human Cdt1 regulation.
