TUBB1 (Tubulin Beta 1) is a gene located on chromosome 9q34.3 that encodes a beta-tubulin isotype primarily expressed in megakaryocytes and platelets, with important roles in neuronal systems as well[1]. While predominantly studied in hematological contexts, TUBB1 has emerging roles in neurodegeneration through its involvement in cytoskeletal dynamics and axonal transport[2].
The TUBB1 protein forms heterodimers with alpha-tubulin to create functional microtubules essential for cellular architecture and intracellular trafficking[3].
TUBB1 encodes beta-1 tubulin, which partners with alpha-tubulin to form microtubule polymers. Its functions include:
While primarily expressed in megakaryocytes and platelets, TUBB1 is also present in:
TUBB1 is relevant to neurodegeneration through:
