TUBA1A (tubulin alpha-1A chain) is a critical member of the α-tubulin family, essential for microtubule formation—a key component of the eukaryotic cytoskeleton. Encoded by the TUBA1A gene located on chromosome 12q13.12. this protein binds to β-tubulin to form heterodimers, which polymerize into dynamic microtubules. These structures support cell division, intracellular transport, and maintenance of cell shape. TUBA1A is particularly vital in neuronal development, regulating neuronal migration, axon guidance, and synaptic function.
Recombinant human TUBA1A is produced via genetic engineering, often using bacterial or mammalian expression systems, to study its biochemical properties and interactions. It typically retains post-translational modifications (e.g., acetylation, detyrosination) when expressed in mammalian cells, enhancing its functional relevance. Researchers use recombinant TUBA1A to investigate microtubule dynamics, neuronal disorders, and screen therapeutic compounds targeting microtubules.
Mutations in TUBA1A are linked to neurodevelopmental disorders like lissencephaly, microlissencephaly, and cortical dysplasia, often causing severe intellectual disability and epilepsy. Studying recombinant TUBA1A aids in understanding these pathologies, enabling mechanistic insights and potential drug development. Its role in cancer progression, particularly in microtubule-targeting chemotherapy resistance, is also an active research area. This protein’s structural and functional complexity underscores its importance in both basic biology and translational medicine.
