Microtubules are microscopic protein filaments found in cells that play a critical role in various cellular processes, including cell division, cell shape, intracellular transport, and cell motility. They are composed of tubulin protein subunits that polymerize to form long, hollow tubes. Microtubules are dynamic structures, constantly growing and shrinking through a process called dynamic instability. Research in the field of microtubules focuses on understanding their structure, function, regulation, and how they interact with other cellular components. This research is important for understanding basic cell biology processes and diseases such as cancer, neurodegenerative disorders, and developmental abnormalities that are associated with microtubule dysfunction. Additionally, microtubules are a target for several chemotherapeutic drugs that disrupt their function and inhibit cell division in cancer cells.
