The CCDC69 gene is involved in encoding a protein that is predicted to enable microtubule binding activity. This protein is crucial for the proper assembly of the spindle midzone, a structure that forms during cell division and is essential for the segregation of chromosomes.
CCDC69 is believed to act as a scaffold protein, regulating the recruitment and assembly of spindle midzone components. It is required for the localization of key proteins such as Aurora B kinase (AURKB) and Polo-like kinase 1 (PLK1) to the spindle midzone . These proteins are essential for the proper progression of mitosis, ensuring accurate chromosome segregation and cell division.
The CCDC69 protein is primarily localized to the spindle midzone during cell division. It has been observed to physically interact with Aurora B kinase, a component of the chromosomal passenger complex (CPC), and other proteins involved in spindle midzone assembly . This interaction is crucial for the stability and function of the spindle midzone.
The recombinant CCDC69 protein is used in various research applications, including:
