Abstract:
Optical methods to modulate microtubule dynamics show promise for reaching the micron‐ and millisecond‐scale resolution needed to decrypt the roles of the cytoskeleton in biology. However, optical microtubule stabilisers are under‐developed. We introduce “STEpos” as GFP‐orthogonal, light‐responsive epothilone‐based microtubule stabilisers. They use a novel styrylthiazole photoswitch in a design to modulate hydrogen‐bonding and steric effects that control epothilone potency. STEpos photocontrol microtubule dynamics and cell division with micron‐ and second‐scale spatiotemporal precision. They substantially improve potency, solubility, and ease‐of‐use compared to previous optical microtubule stabilisers, and the structure‐photoswitching‐activity relationship insights in this work will guide future optimisations. The STEpo reagents can contribute greatly to high‐precision research in cytoskeleton biophysics, cargo transport, cell motility, cell division, development, and neuroscience.
