-tubulin is a core component of microtubules and a member of the tubulin protein family. Multiple -tubulin isotypes are encoded in the human genome, each with distinct patterns of expression and regulation. While certain isotypes are enriched in specific cell types such as neurons or testis, others are expressed more broadly or are induced under stress conditions such as hypoxia or nutrient deprivation. -tubulin antibodies are widely used as immunological tools in cell and molecular biology for studying cytoskeletal organization, cell division, intracellular transport, and other microtubule-related processes.
