Tubulin alpha-8 (TUBA8) is a member of the α-tubulin protein family, which plays a critical role in forming microtubules—dynamic cytoskeletal structures essential for cell division, intracellular transport, and maintaining cell shape. Encoded by the *TUBA8* gene located on chromosome 22q13.1 in humans, this isoform shares conserved structural features with other α-tubulins, including a GTP-binding domain critical for microtubule polymerization. Unlike some α-tubulin isoforms, TUBA8 exhibits tissue-specific expression, with higher levels observed in brain tissues, suggesting specialized roles in neuronal development or function.
Dysregulation of TUBA8 has been linked to neurodevelopmental disorders. For instance, mutations in *TUBA8* are associated with autosomal recessive polymicrogyria-like cortical dysplasia, a brain malformation characterized by abnormal neuronal migration. Its recombinant form, recombinant human TUBA8 protein, is produced via genetic engineering in systems like *E. coli* or mammalian cells, enabling studies on microtubule dynamics, drug interactions, and disease mechanisms. Researchers utilize this tool to explore TUBA8’s unique biochemical properties, such as its divergent C-terminal tail, which may influence microtubule stability or binding partners.
Overall, TUBA8 highlights the functional diversity of tubulin isoforms and underscores their importance in both physiological processes and neurological pathologies. Recombinant TUBA8 continues to serve as a vital resource for dissecting microtubule-related cellular pathways. (Word count: 249)
