CENPC1 (Centromere Protein C1) is a critical component of the centromere, a specialized chromosomal region essential for accurate chromosome segregation during mitosis and meiosis. It plays a pivotal role in maintaining the structural integrity of the centromere and ensuring proper kinetochore assembly, which mediates attachment of spindle microtubules. Human CENPC1 is a conserved protein containing distinct N- and C-terminal domains. The N-terminal domain interacts with centromeric chromatin, including the histone H3 variant CENP-A, while the C-terminal region recruits other kinetochore proteins. Dysregulation or mutations in CENPC1 are linked to chromosomal instability, mitotic errors, and diseases such as cancer. Recombinant human CENPC1 protein, produced via expression systems like *E. coli* or mammalian cells, is widely used in structural studies, functional assays, and drug discovery to dissect centromere biology. Its recombinant form enables researchers to explore molecular mechanisms of centromere organization, kinetochore dynamics, and the impact of pathogenic variants. Studies on CENPC1 also contribute to understanding cell cycle regulation and developing therapeutic strategies targeting mitosis-related disorders.
