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 (By similarity). {ECO:0000250}.

Subcellular Localization

Cytoplasm, cytoskeleton {ECO:0000269PubMed:18849486}.

Disease Associations

Macrothrombocytopenia, autosomal dominant, TUBB1-related (MAD-TUBB1) [MIM:613112]: A congenital blood disorder characterized by increased platelet size and decreased number of circulating platelets. {ECO:0000269PubMed:18849486}. Note=The disease is caused by mutations affecting the gene represented in this entry.

Tissue Specificity

Hematopoietic cell-specific. Major isotype in leukocytes, where it represents 50% of all beta-tubulins. {ECO:0000269PubMed:20191564}.
