**Background of ORC6 Recombinant Protein**
The Origin Recognition Complex (ORC) is a conserved multi-subunit protein complex essential for initiating DNA replication in eukaryotic cells. Comprising six subunits (ORC1-6), it binds to replication origins during the G1 phase of the cell cycle, serving as a platform to assemble the pre-replicative complex (pre-RC). Among these subunits, ORC6 plays a structurally and functionally distinct role. While ORC1-5 form a core ATPase module, ORC6 interacts with this core through flexible linkages, contributing to DNA binding and recruitment of additional replication factors like CDC6 and MCM helicase.
ORC6 is critical not only for replication initiation but also for coordinating cell cycle progression. Studies suggest it participates in cytokinesis and mitotic regulation, linking DNA replication fidelity to cell division. Mutations in ORC6 are associated with developmental disorders (e.g., Meier-Gorlin syndrome) and cancers, highlighting its importance in genome stability.
Recombinant ORC6 protein is produced via heterologous expression systems (e.g., *E. coli* or insect cells), enabling in vitro studies of its biochemical properties, interactions, and role in replication. Purified ORC6 is used to reconstitute functional ORC complexes, analyze DNA-binding kinetics, and screen for inhibitors targeting replication defects in diseases. Its applications extend to structural biology (e.g., cryo-EM studies) and drug development, offering insights into replication mechanisms and therapeutic strategies for cancer and genetic disorders.
In summary, ORC6 recombinant protein serves as a vital tool for dissecting DNA replication dynamics, cell cycle control, and disease pathogenesis, bridging molecular biology with translational research.
