Microtubule nucleation through phase separation

Microtubule nucleation through phase separation

Cells must build cytoskeleton structures, such as microtubules, where they are locally needed within the cell, but how do they do this? In this video abstract, Amayra Hernández-Vega explains that in a test tube, microtubules can be formed locally through phase separation. She also found that the protein Tau can phase separate into droplets, which can then concentrate enough tubulin to nucleate and build microtubules.
