Tubulin beta-1 chain (TUBB1)

Target
TUBB1
Molecular classification
Structural protein, Cytoskeletal protein, GTPase
01

Overview

Tubulin beta-1 chain is a major structural component of microtubules, essential for cell shape, intracellular transport, and mitosis. It forms heterodimers with alpha-tubulins, playing critical roles in microtubule dynamics and spindle assembly. Mutations can affect platelet production and function. The colchicine binding site makes it a target for anti-mitotic cancer drugs.
