DNA replication licensing factor MCM7 is a protein that in humans is encoded by the MCM7 gene. [5]
The protein encoded by this gene is one of the highly conserved mini-chromosome maintenance proteins (MCM) that are essential for the initiation of eukaryotic genome replication. The hexameric protein complex formed by the MCM proteins is a key component of the pre-replication complex (pre-RC) and may be involved in the formation of replication forks and in the recruitment of other DNA replication related proteins. The MCM complex consisting of this protein and MCM2, 4 and 6 proteins possesses DNA helicase activity, and may act as a DNA unwinding enzyme. Cyclin D1-dependent kinase, CDK4, is found to associate with this protein, and may regulate the binding of this protein with the tumor suppressor protein RB1/RB. Alternatively spliced transcript variants encoding distinct isoforms have been reported. [6]
MCM7 has been shown to interact with:
DNA replication licensing factor MCM6 is a protein that in humans is encoded by the MCM6 gene. MCM6 is one of the highly conserved mini-chromosome maintenance proteins (MCM) that are essential for the initiation of eukaryotic genome replication.
Eukaryotic DNA replication is a conserved mechanism that restricts DNA replication to once per cell cycle. Eukaryotic DNA replication of chromosomal DNA is central for the duplication of a cell and is necessary for the maintenance of the eukaryotic genome.
The minichromosome maintenance protein complex (MCM) is a DNA helicase essential for genomic DNA replication. Eukaryotic MCM consists of six gene products, Mcm2–7, which form a heterohexamer. As a critical protein for cell division, MCM is also the target of various checkpoint pathways, such as the S-phase entry and S-phase arrest checkpoints. Both the loading and activation of MCM helicase are strictly regulated and are coupled to cell growth cycles. Deregulation of MCM function has been linked to genomic instability and a variety of carcinomas.
Replication protein A 70 kDa DNA-binding subunit is a protein that in humans is encoded by the RPA1 gene.
DNA replication licensing factor MCM2 is a protein that in humans is encoded by the MCM2 gene.
DNA replication licensing factor MCM3 is a protein that in humans is encoded by the MCM3 gene.
Cell division control protein 6 homolog is a protein that in humans is encoded by the CDC6 gene.
DNA replication licensing factor MCM4 is a protein that in humans is encoded by the MCM4 gene.
CDT1 is a protein that in humans is encoded by the CDT1 gene. It is a licensing factor that functions to limit DNA from replicating more than once per cell cycle.
Origin recognition complex subunit 2 is a protein that is encoded by the ORC2 (ORC2L) gene in humans.
DNA replication licensing factor MCM5 is a protein that in humans is encoded by the MCM5 gene.
Cell division cycle 7-related protein kinase is an enzyme that in humans is encoded by the CDC7 gene. The Cdc7 kinase is involved in regulation of the cell cycle at the point of chromosomal DNA replication. The gene CDC7 appears to be conserved throughout eukaryotic evolution; this means that most eukaryotic cells have the Cdc7 kinase protein.
A-kinase anchor protein 8 is an enzyme that, in humans, is encoded by the AKAP8 gene.
Origin recognition complex subunit 6 is a protein that in humans is encoded by the ORC6 (ORC6L) gene.
Protein MCM10 homolog is a protein that in humans is encoded by the MCM10 gene. It is essential for activation of the Cdc45:Mcm2-7:GINS helicase, and thus required for proper DNA replication.
CDC45 is a protein that in humans is encoded by the CDC45L gene.
80 kDa MCM3-associated protein is a protein that in humans is encoded by the MCM3AP gene.
Dual specificity protein phosphatase CDC14A is an enzyme that in humans is encoded by the CDC14A gene.
DNA polymerase delta subunit 3 is an enzyme that in humans is encoded by the POLD3 gene. It is a component of the DNA polymerase delta complex.
Origin recognition complex subunit 1 is a protein that in humans is encoded by the ORC1 gene. It is closely related to CDC6, and both are the same protein in archaea.
