Minichromosome maintenance protein 7 (MCM7) is a nuclear DNA replication factor encoded by the MCM7 gene and functions as a key component of the minichromosome maintenance helicase complex that drives eukaryotic DNA replication. MCM7 Antibody Rabbit Polyclonal is designed to recognize this replication licensing protein and supports research focused on cell cycle regulation, DNA synthesis, and proliferative activity in normal and malignant cells. MCM7 belongs to the conserved MCM protein family and participates in the MCM2-7 helicase complex that unwinds double-stranded DNA during the initiation and elongation phases of DNA replication.
During early cell cycle stages, MCM proteins assemble onto chromatin at replication origins as part of the pre-replication complex. MCM7 interacts with other helicase subunits including MCM2, MCM3, MCM4, MCM5, and MCM6 to form the hexameric helicase ring responsible for separating DNA strands at replication forks. This activity allows DNA polymerases and associated replication machinery to access single-stranded DNA templates and accurately duplicate the genome during S phase. Because of this essential function, the MCM complex is often referred to as a DNA replication licensing system that ensures chromosomal DNA is replicated once per cell cycle.
MCM7 antibody, also referred to as CDC47 antibody and P1-MCM3 antibody in the literature, detects a replication-associated nuclear protein that is strongly expressed in actively dividing cells. The protein localizes primarily to the nucleus where it associates with chromatin during DNA synthesis. Expression of MCM7 is typically elevated in proliferating cell populations and reduced in quiescent or terminally differentiated cells, making it a useful indicator of cellular proliferation in many experimental systems.
At the molecular level, MCM7 contains conserved ATP-binding and ATP-hydrolysis domains that belong to the AAA+ ATPase family of helicase proteins. These domains provide the energy required for conformational changes within the helicase complex, enabling DNA strand separation and replication fork progression. Through these mechanisms, MCM7 plays an important role in maintaining genomic stability and coordinating DNA replication with cell cycle checkpoints. Disruption of MCM7 expression or activity can interfere with replication licensing and contribute to abnormal cell cycle progression.
Elevated expression of MCM7 has been reported in multiple cancer types, including colorectal carcinoma, breast cancer, and lung cancer, reflecting the increased DNA replication activity associated with rapidly proliferating tumor cells. Because of its strong nuclear localization and association with S-phase cells, the protein is widely studied in cancer biology, cell proliferation research, and studies of replication origin regulation. A rabbit polyclonal MCM7 Antibody Rabbit Polyclonal provides a useful tool for detecting Minichromosome maintenance protein 7 expression and studying the cellular mechanisms that regulate DNA replication and cell cycle progression.
The stated application concentrations are suggested starting amounts. Titration of the MCM7 Antibody Rabbit Polyclonal may be required due to differences in protocols and secondary/substrate sensitivity.
An amino acid sequence from the C-terminus of human MCM7 (DEYEELNVWQVNASRTRITFV) was used as the immunogen for this MCM7 antibody.
After reconstitution, the MCM7 antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing.
