Biological process

down regulation of microtubule depolymerization, down-regulation of microtubule depolymerization, downregulation of microtubule depolymerization, microtubule stabilization, negative regulation of microtubule disassembly

Any process that stops, prevents, or reduces the frequency, rate or extent of microtubule depolymerization; prevention of depolymerization of a microtubule can result from binding by 'capping' at the plus end (e.g. by interaction with another cellular protein of structure) or by exposing microtubules to a stabilizing drug such as taxol.
