CENPT (Centromere Protein T) is a critical component of the centromere, a specialized chromosomal region essential for accurate chromosome segregation during cell division. It is part of the constitutive centromere-associated network (CCAN), a multi-protein complex that stabilizes kinetochore assembly and facilitates microtubule attachment. CENPT directly interacts with centromeric DNA through its conserved C-terminal histone-fold domain, which forms a heterodimer with CENPW, while its N-terminal region mediates connections with other CCAN proteins. This structural arrangement ensures proper centromere identity and function. Dysregulation of CENPT disrupts mitotic progression, leading to chromosomal instability—a hallmark of cancers and genetic disorders. Recombinant CENPT, produced via genetic engineering, enables in vitro studies of its DNA-binding properties, protein interactions, and role in epigenetic centromere maintenance. Recent structural analyses using cryo-EM and X-ray crystallography have clarified its DNA recognition mechanism and disease-linked mutations. Pharmacological targeting of CENPT is being explored to mitigate chromosome missegregation in malignancies, though its essential role in normal cells poses challenges for therapeutic development.
