**Background of TBCB Recombinant Protein**
TBCB (Tubulin Folding Cofactor B) is a critical member of the tubulin-specific chaperone family, which facilitates the proper folding and assembly of α-tubulin into functional heterodimers with β-tubulin. These heterodimers serve as building blocks for microtubules, dynamic cytoskeletal structures essential for cell division, intracellular transport, and maintenance of cell shape. TBCB works in concert with other cofactors (e.g., TBCE, TBCA, and Arl2) to ensure the correct folding and stability of α-tubulin, preventing its aggregation or degradation.
Recombinant TBCB protein is engineered using genetic engineering techniques, where the *TBCB* gene is cloned into expression vectors and produced in host systems like *E. coli*, yeast, or mammalian cells. This allows large-scale production of purified, biologically active TBCB for research and therapeutic applications. Its recombinant form retains the ability to bind and stabilize α-tubulin, making it invaluable for studying microtubule dynamics, neurodevelopmental disorders, and diseases linked to tubulin dysregulation, such as cancer and neurodegenerative conditions.
Research utilizing TBCB recombinant protein has shed light on its role in microtubule-related pathologies. For instance, mutations in tubulin chaperones are associated with microcephaly and motor neuron diseases. Additionally, TBCB is implicated in cancer progression, as altered microtubule stability affects cell division and metastasis. The recombinant protein also serves as a tool for drug screening, particularly for compounds targeting microtubule-modulating pathways.
Despite its utility, producing functional TBCB recombinant protein requires optimization of expression conditions to address solubility and post-translational modification challenges. Advances in structural biology and proteomics continue to refine its applications, positioning TBCB as a pivotal target for both basic research and therapeutic development.
