TUBB6 encodes tubulin beta 6 class V, a structural component of microtubules that plays specialized roles in cellular differentiation, migration, and pathological processes. As a microtubule constituent, TUBB6 forms heterodimers with alpha-tubulin to create the cylindrical structures essential for cytoskeletal organization 1. TUBB6 expression is particularly elevated in osteoclasts, where it is essential for podosome organization and sealing zone formation required for bone resorption activity 1. The protein also facilitates cellular migration and invasion, as demonstrated in bladder cancer where TUBB6 promotes muscle invasion and correlates with poor prognosis 2. In ocular diseases, TUBB6 drives pathological angiogenesis through the WNT3A-FZD8 pathway, with YBX1 regulating its mRNA stability 3. During muscle regeneration, TUBB6 upregulation contributes to microtubule reorganization, though chr18 elevation may contribute to dystrophic pathology 4. Additionally, TUBB6 functions as a long non-coding RNA in neuroprotection, activating the Nrf2 pathway to suppress inflammation and ferroptosis after traumatic brain injury 5. The gene has also been associated with focal segmental glomerulosclerosis 6 and ocular congenital cranial dysinnervation disorders 7, highlighting its diverse roles in development and disease.
