Tubulin (vinca domain)

Molecular classification
Cytoskeletal protein complex, Tubulin
01

Overview

The tubulin vinca domain is a specific binding site on the tubulin protein, a key component of microtubules. It is located at the interface between α- and β-tubulin subunits. This domain is the target for several antimitotic agents used in cancer therapy, such as vinca alkaloids (e.g., vinblastine, vincristine). Drugs targeting the vinca domain inhibit microtubule polymerization, leading to mitotic arrest and apoptosis in rapidly dividing cells.
