What is the official name of the CDT1 gene?
The official name of this gene is “chromatin licensing and DNA replication factor 1.”
CDT1 is the gene's official symbol. The CDT1 gene is also known by other names, listed below.

What is the normal function of the CDT1 gene?
The CDT1 gene provides instructions for making a protein that is important in the copying of a cell's DNA before the cell divides (a process known as DNA replication). The protein produced from this gene is one of a group of proteins known as the pre-replication complex. In a multi-step process, the components of this complex attach (bind) to certain regions of DNA known as origins of replication (or origins), where the process of DNA copying begins. When the pre-replication complex is attached to the origin, replication is able to begin at that location. This tightly controlled process, called replication licensing, helps ensure that DNA replication occurs only once per cell division and is required for cells to divide.
