Target intelligence / Profile preview

Microtubule (specifically β-tubulin within assembled microtubules) (MT)

Target
MT
Molecular classification
Cytoskeletal protein, Structural protein
01

Overview

Microtubules are essential components of the cytoskeleton involved in cell division, intracellular transport, and maintenance of cell shape. Paclitaxel and docetaxel bind to β-tubulin within assembled microtubules, stabilizing them and preventing depolymerization. This leads to mitotic arrest and apoptosis, making them effective anticancer agents.

Mechanism of action

Prevents microtubule depolymerization, leading to microtubule stabilization, mitotic arrest at G2/M phase, and induction of apoptosis.
