CDT1 (Cdc10-dependent transcript 1) is a protein involved in the regulation of the cell cycle, specifically in the DNA replication process. It plays a crucial role in the initiation of DNA replication by helping to load the minichromosome maintenance (MCM) complex onto chromatin. CDT1, along with CDC6, is essential for the formation of the pre-replication complex (pre-RC) during the G1 phase of the cell cycle.
