Cell division control protein 6 homolog is a protein that in humans is encoded by the CDC6 gene. The protein encoded by this gene is highly similar to Saccharomyces cerevisiae Cdc6, a protein essential for the initiation of DNA replication. This protein functions as a regulator at the early steps of DNA replication. It localizes in the cell nucleus during cell cycle phase G1, but translocates to the cytoplasm at the start of S phase. The subcellular translocation of this protein during the cell cycle is regulated through its phosphorylation by cyclin-dependent kinases. Transcription of this protein was reported to be regulated in response to mitogenic signals through a transcriptional control mechanism involving E2F proteins.

Interactions

CDC6 has been shown to interact with ORC1L, ORC2L, Cyclin A2, PPP2R3B, MCM3, PPP2R3A, MCM7 and PSKH1.
