Function

Tubulin is the major constituent of microtubules. It binds two moles of GTP, one at an exchangeable site on the beta chain and one at a non-exchangeable site on the alpha chain.

Subcellular Localization

Cytoplasm, cytoskeleton.

Disease Associations

Tissue Specificity

Ubiquitous. {ECO:0000269PubMed:20191564}.
