Post-translational modifications are essential regulators of cell migration. Discover how phosphorylation, ubiquitination, acetylation, SUMOylation, methylation, and lipid modifications control cytoskeletal dynamics, focal adhesions, cell polarity, and cancer invasion.

Asymmetric cell division produces daughter cells with different sizes, molecular compositions or developmental fates. Guided by polarity complexes, spindle orientation and unequal segregation of determinants such as Numb and Prospero, this process maintains stem‑cell pools, drives tissue development and prevents uncontrolled proliferation. Its disruption contributes to degenerative disease and cancer.
