CENPF (Centromere Protein F), also known as mitosin, is a large nuclear protein crucial for cell division, particularly during mitosis and meiosis. It plays essential roles in chromosome segregation, kinetochore assembly, and cell cycle regulation. Structurally, CENPF contains multiple functional domains, including an N-terminal region involved in microtubule binding and a C-terminal domain that interacts with other centromere components. Its expression peaks during the G2/M phase of the cell cycle, correlating with its mitotic functions.
Recombinant CENPF protein is engineered using molecular cloning techniques, typically expressed in mammalian or bacterial systems with affinity tags (e.g., His-tag) for purification. This biotechnologically produced protein retains native structural and functional properties, enabling in vitro studies of its interactions with chromosomal DNA, microtubules, and regulatory partners like CENP-E and Aurora kinases.
Research applications include investigating mechanisms of aneuploidy, cancer biology (CENPF overexpression is linked to poor prognosis in multiple cancers), and congenital disorders related to mitotic errors. Recombinant CENPF also serves as an antigen for antibody development and a tool for drug screening targeting cell cycle dysregulation. Its ~350 kDa size and dynamic phosphorylation patterns (regulated by CDK1/cyclin B1) make it a valuable model for studying post-translational modifications in protein function. Current studies focus on its non-mitotic roles in nuclear envelope reassembly and transcriptional regulation, expanding its therapeutic relevance in proliferative diseases.
