Protein microtubules take part in several cellular activities including mitosis, cell movement and migration. During these
cellular activities, they can be subject to various types of external loading and pressure. In this study, the bucking of protein
microtubules obtained via scale-dependent continuum models are investigated. Several continuum-based formulations, which have
been proposed for the buckling of protein microtubules, are reviewed briefly. Finally, the effects of surface elastic properties on the
growth rate of buckling in protein microtubules are studied.
