2. Figure 1 Microtubule self-repair and rescue.
Top: Growing microtubules may acquire lattice damage during growth (blue arrow), potentially as a result of collisions with other microtubules. Middle: GTP-tubulin subunits may then ‘fill in’ the lattice defect, generating an island of GTP-tubulin within the microtubule lattice (red GTP-tubulin subunits at blue arrow). Bottom: After a stochastic catastrophe event, a GTP-tubulin island may slow microtubule shortening, and thus increase the probability of a rescue event that originates at the island.
