CEP55 inhibitors belong to a class of compounds specifically designed to target the protein CEP55, which plays a crucial role in cellular processes related to cell division. CEP55, or centrosomal protein 55, is a key regulator of cytokinesis, the final stage of cell division, where the cytoplasmic content is divided between the two daughter cells. This protein is predominantly localized to the centrosomes and midbody during mitosis, essential cellular structures orchestrating the proper segregation of chromosomes and the formation of the cleavage furrow.
The inhibitors designed for CEP55 work by disrupting its activity or binding to its specific sites, thereby impeding its normal function in cytokinesis. By interfering with CEP55, these inhibitors aim to induce abnormalities in cell division, leading to the generation of cells with defective or incomplete cytokinesis. This disruption can result in cellular stress, triggering mechanisms such as apoptosis or senescence. The development of CEP55 inhibitors is rooted in a deeper understanding of the intricate molecular processes governing cell division. Researchers are exploring these inhibitors not only to gain insights into fundamental cellular biology but also to investigate their potential implications in various pathological conditions, as aberrant cell division is often associated with diseases like cancer.
