CENPL (Centromere Protein L) is a crucial component of the constitutive centromere-associated network (CCAN), a multi-protein complex essential for proper kinetochore assembly and chromosome segregation during cell division. Encoded by the *CENPL* gene in humans, this evolutionarily conserved protein plays a pivotal role in maintaining genomic stability by ensuring accurate microtubule attachment and sister chromatid separation. Structurally, CENPL interacts with other CCAN subunits (e.g., CENP-A, CENP-C) to form a foundation for kinetochore formation, linking centromeric chromatin to the outer kinetochore machinery.
Recombinant human CENPL, produced via genetic engineering in bacterial or eukaryotic expression systems, enables detailed mechanistic studies of centromere biology. Its recombinant form is widely used to investigate centromere assembly, mitotic checkpoint signaling, and errors linked to chromosomal instability—a hallmark of cancer and genetic disorders. Research on CENPL also explores its potential as a therapeutic target, given its involvement in preventing aneuploidy. Mutations or dysregulation of CENPL have been associated with developmental defects and tumorigenesis, highlighting its biomedical relevance. Studies leveraging recombinant CENPL contribute to understanding cell cycle regulation and designing strategies to correct segregation defects in diseases.
