How cells keep in shape

Researchers at EMBL and AMOLF discovered a new experimental approach to study microtubule end tracking proteins, which are crucial for cell shape development. The study sheds light on the interaction between proteins and the cell's skeleton, revealing how +TIPs recognize dynamic microtubule ends.
