Centriole, Cilia and Spindle Associated Protein", commonly abbreviated as "CSAP", is a protein that plays a critical role in the structural integrity and function of centrioles and cilia, which are essential components of the cytoskeleton in eukaryotic cells. Centrioles are cylindrical structures that are key for the formation of centrosomes and cilia, while cilia are hair-like projections that can either move to propel cells or remain static to sense environmental cues.CSAP is thought to be centrally involved in the assembly and stability of centrioles. By associating with these structures, CSAP helps in maintaining their proper number and function. This is crucial for normal cell division, as centrioles organize spindle fibers that segregate chromosomes during mitosis and meiosis.

In terms of ciliary function, CSAP is implicated in the formation and maintenance of cilia, which play a vital role in signaling pathways and fluid movement across the cell surface. The protein is believed to support the ciliary structure, contributing to the proper formation of the axoneme-the core skeleton of a cilium-and ensuring that ciliary function is preserved.Additionally, CSAP is associated with the spindle apparatus, which aligns and separates chromosomes during cell division. It helps in stabilizing microtubules, thereby ensuring accurate chromosome segregation and preventing aneuploidy, a condition where cells have an abnormal number of chromosomes that can lead to developmental disorders and cancer.Mutations in the gene encoding CSAP can lead to defects in cell division and ciliary function, which may result in a range of ciliopathies-disorders caused by dysfunctional cilia-and contribute to the development of cancer due to errors in chromosome segregation. Therefore, CSAP is a critical protein for the orderly progression of the cell cycle and for the signaling functions of cilia in cellular homeostasis and development.
