an essential licensing protein for DNA replication. Cooperates with CDC6 to promote the loading of the mini-chromosome maintenance complex onto chromatin to form the pre-replication complex necessary to initiate DNA replication. Binds DNA in a sequence-, strand-, and conformation-independent manner. Elevated in all human tumor cell lines analyzed. May function as an oncogene in mammals. Interaction with GMNN inhibits both binding of the MCM complex to origins of replication and DNA-binding activity. Present during G1 and early S phase of the cell cycle. Degraded during the late S, G2, and M phases. Note: This description may include information from UniProtKB.
