Microtubules acquire resistance from mechanical breakage through intralumenal acetylation

Acetylation keeps microtubules strong Cells need microtubules for intracellular transport and to avoid being crushed. On investigating microtubule breakage in live fibroblasts, Xu et al. found that if they were not acetylated, long-lived microtubules underwent frequent rupture after buckling. Acetyl... View More
