The cytoskeleton
The cytoskeleton, a complex network of protein filaments, serves as the architectural backbone of eukaryotic cells. Comprised of microfilaments, intermediate filaments, and microtubules, it provides structural support, cell shape, and motility. Functionally versatile, the cytoskeleton plays crucial roles in cell division, endocytosis, and exocytosis. Regulated by specific proteins, its dynamic nature underlies various cellular processes.…
