**Background of CENPM Recombinant Protein**
CENPM (Centromere Protein M) is a critical component of the centromere-associated protein complex, essential for proper chromosome segregation during cell division. It plays a pivotal role in the assembly and stabilization of the kinetochore, a structure that mediates attachment between chromosomes and spindle microtubules. CENPM is part of the constitutive centromere-associated network (CCAN), which ensures the fidelity of mitosis and meiosis by maintaining centromere identity and regulating sister chromatid cohesion. Dysregulation of CENPM has been linked to chromosomal instability, a hallmark of cancers and genetic disorders.
The recombinant CENPM protein is engineered using molecular cloning techniques, typically expressed in *E. coli* or mammalian cell systems, followed by purification to achieve high homogeneity. This recombinant form retains the functional domains of native CENPM, enabling studies on its interactions with other centromere proteins (e.g., CENP-A, CENP-C) and its role in epigenetic centromere maintenance. Researchers utilize CENPM recombinant protein to investigate mechanisms underlying mitotic errors, develop biomarkers for cancer diagnostics, or screen for therapeutic agents targeting centromere dysfunction.
Structurally, CENPM contains conserved motifs that facilitate DNA binding and protein-protein interactions, critical for its localization to centromeres. Its recombinant version is invaluable in *in vitro* assays, such as pull-down experiments, kinase activity assays, and structural studies (e.g., crystallography). Additionally, it aids in producing antibodies for immunohistochemical applications. Ongoing research focuses on elucidating how CENPM mutations contribute to diseases and exploring its potential as a target for anticancer therapies.
