General description

DNA replication protein Cdc45 (UniProt: Q4U3P7; also known as Cdc45) is encoded by the CDC45 gene (Gene ID: 100689362) in hamster. Cdc45 is a replication initiation protein that plays an essential role in the establishment and progression of the replication fork. It is required for formation of pre-initiation complexes at the G1/S transition and for activation of replication origins. Cdc45 associates with the heterohexameric Mcm2-7 helicase and the GINS complex (go-ichi-nii-san, Japanese for 5-1-2-3, for the subunits Sld5, Psf1, Psf2 and Pfs3) to form the CMG (Cdc45-Mcm2-7-GINS) complex. CMG represents the eukaryotic replicative DNA helicase that unwinds origins of replication and drives the replication fork. Cdc45 is also reported to interact with several other replication proteins, including DNA helicase B (DHB), Mcm10, Orc2, TopPB1, and DNA polymerases alpha, delta and epsilon. Expression of Cdc45 is associated with the proliferative status of the cell or tissue. Terminally differentiated and senescent cells do not display Cdc45 activity whereas highly proliferative cells express high levels of Cdc45.
